Oh Soccer Mom... yikes! I'm not married, but I don't think I'd want to talk about T to a husband/boyfriend/etc. It just feels so personal. I understand that there are some things that are important to share so that you both can parent effectively, but I don't think you (or anyone) needs the additional stress of having your husband question your therapy and tell you that since it's going to painful to end, you should just end it now (!!!).

Is it possible for you to just put a boundary around this? Like, "I know you don't fully understand why I need therapy, but I do need therapy and plan to continue. I'd like to share some of the insights and work I do around parenting with you, but other than that, I'm going to consider it personal and would prefer not to discuss it."

I don't know, maybe that's not appropriate for what the situation is - but you get the idea? Because, really, T is hard enough... you don't need someone encouraging you to leave!
