I typed out a whole response and it didn’t post, argh.

Your feelings are perfectly understandable for someone who has been cheated on. Therapy should help. Maybe DBT can help because it gets you to think about what to do if the worst should happen and that helps with the anxiety.

I believe there are cheaters and non cheaters. It’s that simple. The non cheaters won’t cheat. It sounds like your husband is a non cheater and I hope therapy will help you learn to feel secure and trust him.
