Hey A, it sounds like you had a nice weekend. I am happy for you. Hope your head doesnt hurt too badly - LOL!
I would only suggest that when he says things like I dont know if we could work it out or I dont know if we could trust each other, to perhaps not say much. He is feeling you out, testing you. The less you say the better. I know it is hard to believe, but, everything feels like pressure to them. So, listen, validate that you heard by saying, I am sorry you feel that way or I understand how you might feel that way and thats it. Keep it short and sweet, ya know?
