Hi, My boyfriend and I have been in a long distance relationship for about two years now. We have been friends for over three years as we were in the same college. We were seeing other people before we started dating. He is super insecure and we have had multiple disagreements and arguments over me being in touch with my guy friends. He, however, is super social and has many female friends in his inner friends' circle. He is in touch with all his exes and although I am not super happy about it, I don't mind either.
Recently, he travelled to another city for some work(as he says but i am highly suspicious about) and chose to stay at his ex's place. I wasn't happy by the idea and told him upfront that i would be hurt if he stays with her. He still chose to stay at her place and hardly contacted me all the while (just two messages and no calls in three days). I don't even know if his ex is aware of his relationship with me. He says he loves me and he is very loyal and did nothing wrong, but somehow I am not convinced. I feel insulted and de-valued. What am I supposed to do? Am I overthinking?
