He is what we call a borderline personality disorder. They are arrogant and overconfident. They do not care about anyone else's needs. They live to be the center of attention and are over dramatic. Most of all they are manipulative and prefer chaos over stable relationships. They are your friend or your enemy. An insinuation that they will hurt themselves is very common. They rarely do it . They rather get attention through hysterics. Drop him immediately! This is will not change. He will continue to do things to get attention and put his needs above yours. He will not change. They are full of empty promises. Cut it off clean and don't look back. Tell him it's over and let it go. He will move on eventually
If this is helpful press accept
If you have talked about this and you both agreed that you want to try again, then chances are he isn't going to change his mind. He was pursuing you = he is motivated to start this relationship on the premise that you have alot to talk about. I would spend time thinking about what you want from the relationship and what issues need to be resolved. You could start a journal with this information to take your mind off being away. You are just having anxiety about this. Talking will reassure you again. I would use journaling to get through the week and be prepared to ask for what you want.
