A Client Messages the Therapist Between Sessions: How to Set a Boundary Without Breaking the Alliance
A client messages her therapist regularly — in the evenings, on weekends, sometimes just to share what happened during the day. Setting a boundary feels hard — it brings up guilt, as if refusing equals withholding support. At the same time, the therapist notices her own anger, a sense of being overwhelmed, an urge to ignore the message — followed immediately by fresh guilt over that very ignoring.
Definitions
Therapy-interfering behavior — per Marsha Linehan — any client behavior that mirrors the same difficulties troubling them outside of therapy; it requires direct therapist attention rather than being ignored.
Therapeutic alliance — the working, trusting relationship between therapist and client. Key idea: a well-set boundary is not just an administrative rule but can itself be part of the therapeutic intervention.
What a Message Between Sessions Might Mean
| Behavior | Possible Meaning |
|---|---|
| Frequent messages | seeking emotional support |
| Messages during a crisis moment | attempting to restore a sense of safety |
| Reaction to a limit on contact | testing the stability of the relationship |
| Repetition despite agreements | material to explore a pattern, not necessarily manipulation |
Why This Isn't Only a Matter of Discipline
Marsha Linehan notes that client behavior reflecting difficulties outside therapy — demandingness, hostility, a pattern echoing their close relationships — shouldn't be ignored until it's too late. One of the most common and dangerous mistakes is tolerating mounting strain silently until the therapist's resources are exhausted, then abruptly ending therapy in a way that leaves the client confused and feeling at fault.
The therapist here has already noticed an early sign of this pattern — irritation, occasional ignoring. That's a cue to name what's happening now, rather than endure it hoping it will resolve on its own.
What's Worth Clarifying Before Setting a Boundary
Irina Bulyubash describes a similar dynamic: a client who feels unsupported but can't ask for it directly. In the supervision example from her book, a therapist facing strong helplessness and guilt risks reacting the same way the client's environment does — asking 'how can I help,' instead of clarifying what the client is actually seeking through this behavior.
In this situation, the therapist has already made an important observation: the client behaves this way with everyone, not just her. The question shifts from 'is it right to set a boundary with this particular client' to 'what does this say about her habitual way of relating, and how can therapy make that visible.'
Before Setting a Boundary, It Helps to Ask Yourself
- What exactly is triggering my guilt?
- What happens to me after each message?
- Is there a recurring pattern in my reaction?
- What does this say about our therapeutic relationship?
How to Set the Boundary
- Explore the function of the messages: 'I've noticed you write to me often. That shows how important support is to you. Tell me what exactly you're looking for when you send a message?'
- Name the boundary clearly, without an apologetic tone: if the format of the work doesn't include contact between sessions, the therapist typically doesn't respond between meetings, and anything important can be discussed in detail at the next session. If exceptions are agreed on in advance, they should be named explicitly.
- Support the client's ability to seek support elsewhere too, not only from the therapist — this is tied to her growth, not just the therapist's convenience.
- Track one's own anger and guilt as countertransference material, without suppressing it or acting on it impulsively.
- If one's own reactions remain consistently intense, bring the situation to supervision.
When Contact Between Sessions Is Normal
Sometimes contact between sessions is built into the format of the work in advance — for instance, in certain DBT variants, crisis work, or other structured approaches. In that case the question isn't the fact of messaging itself, but the pre-agreed rules: when it's okay to write, for what reasons, and what response to expect.
Common Therapist Mistakes
- Silently tolerating the strain, hoping it resolves on its own — per Linehan, a direct path to an abrupt, painful rupture in therapy later.
- Setting the boundary with an apologetic, uncertain tone — this often signals to the client that the boundary can and should be tested.
- Impulsively ignoring messages without explanation — leaves the client in uncertainty instead of giving the structure they actually need.
- Immediately interpreting the behavior as manipulation, without trying to clarify the real need behind it.
When Boundaries Are Secondary
If messages between sessions contain clear signs of an acute crisis — threats to life, active suicidal state — the usual boundary work is set aside: risk assessment becomes the priority. The therapist should clarify, before therapy begins, a protocol for crises between sessions — where to turn if the state becomes acute — so that the therapist's silence isn't experienced as the only available channel in a dangerous moment.
What's Worth Remembering
- messages between sessions don't always mean manipulation;
- the function of the behavior matters more than the behavior itself;
- a clearly set boundary can strengthen the therapeutic alliance rather than break it;
- the therapist's guilt and anger are meaningful countertransference material;
- in a crisis, the client's safety is assessed first, and rules about contact are discussed afterward.
Frequently Asked Questions
Will setting a boundary break the therapeutic alliance?
Not necessarily. How the boundary is introduced — with clarity and respect rather than apology or coldness — affects the alliance more than the fact of the boundary itself.
Does a client's persistent behavior mean manipulation?
Not always. It often reflects a broader pattern in how the client relates to people in general — it's worth clarifying the real need behind the behavior before concluding it's manipulation.
What should you do with your own irritation and guilt toward the client?
Don't suppress it or act on it impulsively — recognize it as valuable countertransference material and, if it stays consistently intense, bring it to supervision.
When do messages between sessions call for a risk assessment rather than a boundary conversation?
When they signal an acute crisis or suicide risk — then the client's safety becomes the priority, and the conversation about communication rules is set aside for the moment.
Practical Takeaway for the Therapist
If guilt over trying to set a boundary is persistent and strong, that's a signal to bring the situation to supervision rather than resolve it through willpower alone in the moment.
