A guy who i was recently seeing found out that i use to hook up with one of his aquaintance but it seems more like a friend based on how he reacted. The only thing is this happened long before i met this guy and now he says that he's upset and “doesn’t know what to do”. Why would he make sometime from the past a big deal? Could he be lying to me saying they’re not friends or is he just overreacting everything? Or did he just lose respect for me all of a sudden?
