Me & my ex broke up YEARS ago now, and we've been friends ever since. He moved away and so did I, so now we're miles and miles apart. I'm at university and he's working abroad. We're very close and don't usually fight, but recently I became involved with a friend of mine sexually and since then me and my ex have been arguing non-stop. In our last blazing argument he said I didn't appreciate him or understand him and that I'm more loyal to the guy I've been sleeping with than I am to him, and that I'm trying intentionally to hurt his feelings by what I've been doing. I HONESTLY am not, but he doesn't believe me, and now he's been acting really moody and I don't understand why. He has a really stressful job so I try to give him a break when I can and always try to listen to him and help him out, so I'm feeling really hurt that he's said all this stuff to me. What can I do to sort this out?!
