I have a boyfriend who had girlfriends before we meet. Apparently, he had quite a few EXes. I told him that it's OK with me if he talks to them BUT he must let me know. Sad to say, whenever one of his EXes tries to contact him he hides it from me, deleting their conversation. I always get mad about this but this is the third or fourth time that he did this. I can't always forgive him for doing so. What shall I do? We've been together for 2 years. 😞
