When I started therapy a long while back, I started with a marriage and family therapist. As part of the first session, he told me that there's a slight increased risk for divorce when only one person goes to marriage and family therapy. I don't know if it's true.

But... the same thing happened to me that you described. In addition my husband was very anti-therapy. Things have changed a bunch in our marriage. Our relationship was way harder after I started therapy, but I think if we had kept on going the way we were going before I started therapy, one of us would have left by now. We were growing more and more distant. My husband resisted a lot of my changes, but eventually I got used to dealing with the resistance. (I cried a lot over it though.)

It was a risk because I didn't know if he would still like me. I got used to speaking up for what I needed and wanted though and I felt a whole lot better. We have a pretty OK marriage now. It could be better, but we're still together and we still enjoy hanging out together. We are much better at communicating now than when we first got married.

But yeah, it was pretty scary a bunch of times, especially when I realized, either things change or I have to leave. Good luck.
