I would be extremely frustrated and annoyed too, even without the last summer incident. I think constantly texting when you are out with others is rude whether it's a spouse or a friend.

I do find it concerning that his friends are hidden from you. My husband has several female friends, most of whom I've met or at least spoken to on the phone.

I don't know what the answer is - maybe you can see a therapist to find out how to deal with this better - maybe if you change how you react to him it will assist in changing how he behaves. I know when I change how I reach to my husband it does help him change how he acts.

Hope that helps and I hope it gets better.
