I had a fling with one of my best friend's brothers. Things got pretty serious, though it would eventuate due to long distance (10 hours between us). So I contacted him and told him how I felt. He cut contact with me for 2 months. I was very upset, because I thought we could at least remain friends - as he's my best friends brother and things needed to stay civil. I moved on though. However, just as I moved on, he has started contacting me again. His tone is quite cold, though he is the one initiating contact, and he says immature things such as "fine then" when I text him that I'm going to sleep. It's making me feel like I've done something really wrong and I'm getting the vibe that he is hung up on me. Do you think this is the case? Because realistically, why is a man choosing to contact me when he lives 10 hours away? It should be easy for him to forget and move on. It's really messing with my head. What should I do to make this stop without putting strain on my relationship with my best friend - as they are very close.
