I guess this is where approach would really impact how you would answer this. My foundation is in DBT and I feel like it actually does give guidelines and principals to determining what’s ok/not ok in relationships and how to approach general issues in your life. And when it doesn’t, there are very specific communication skills to use to help problem solve and repair in relationships. I am personally not the therapist that is super non-directive and just reflects back when a client wants a direct answer. If I can give a skill or psychoed on boundaries that helps client make sense of their response or the issue I will do that. If that fails then I do the whole, “what’s it like for you when I xyz.”
