@Coconuts75,
Why would you go to a therapist if you can't open up to him/her?
Friends are whatever you want to see in them and perhaps you're asking too much of a friendship. Sometimes meeting for a cup of coffee and talking about
every day life is already enough to enjoy the other person. If you're looking
to confide in a friend, have a close relationship with them then you need to open up to them as much as they would. Judging from your writing, you're not willing to open up to others, then an superficial get together should be sufficient for you.
As for your husband, I don't now what to say - if he intentionally enjoys hurting you, stabs the knife in your back the minute you turn around, the relationship is flawed and since you can't trust him, it's a doomed situation. Trust is the first and foremost requirement for a successful marriage and if I can't trust my partner there is no use for me to stay in a relationship.
I gather from your post that you're middle aged, you should know what you want from a marriage, a relationship and out of your life. You either act on it or you remain with the status quo. The choice is yours!
