Well first off, your boyfriend is very insecure... Then again we all are at one point or another, but he just takes it to an extreme. I think you need to have a straight forward talk with him and tell him that you don't want to put up with it anymore. He can try to change, and he may change, but in my opinion, chances are very slim. He probably feels that you are a very special person in his life and he doesnt want to lose you. He probably also feels like he is competing with your past. He wants to make sure that he is better than everyone else you may or may not have been involved with. Like I said, you have to be straight with him, tell him that you are with him for a reason and if there were someone in your past that you wanted to be with, then you would be with them and not him. But the truth of the matter is that you are with him and there is a reason for that. Explain to him that he has nothing to worry about and that you want him to try and stop bringing up your past or being insecure about every little thing... And if he can't do that then you will have to either move on or live with it. Becuase the truth is, people don't really change to please others, he has to want to change or else he may just change temporarily and then go back to his same old ways... But yeah, thats just my opinion. I hope it works out though. Just let him know: you are with him for a reason and you've stuck with him for a reason, so he has nothing to worry about. :)

He is very insecure and jelous. Ive been with my boyfriend for 4 years. I would act the same way. You have every right to be fed up and pissed off because my boyfriend would alway say the same thing "ive been with your almost 4 years and you still have to ask questions and think im leaving you?". What I did was seek therapy, and I also went on medication to help with my anxiety because I was always worried he would leave me, cheat on me etc. My boyfriend has seen a huge change in me in the last 6 months and things that bothered me before no longer do. Your boyfriend has some issues either past childhood issues or just general problems, he needs to speak with someone, because he is a man he probably wont but you can only take so much. If I didnt get help I would have lost the best thing that ever happened to me. If he doesn't change you will have to give him the option to get help or end the relationship. If he cares that much he will do whatever he can to change but he has to realize for himself that he needs help. He wont change on his own hun trust me. I wish you the best of luck you seem like a great girlfriend and you don't deserve to deal with his issues because you did nothing wrong.
