Agree. I would say that is reciprocal though: It's just usually better for therapists if clients' own stuff isn't leaking into the therapist's personal life. I don't think that happens too terribly often (and I don't think that applies to the OP at this point at all), but it can happen and when it does it can become problematic. I do think that on those occasions when it does happen (again, don't think that is the case yet with the OP), the therapist has to decide how to best handle that kind of intrusion with the individual client. I would suspect it can often be handled with discussion with the client, but if that doesn't improve the situation, then the therapist might have make decisions regarding their own sense of comfort and safety.
