How to deal with a major jealous and paranoid boyfriend?

Leave. You deserve to have someone in your life whose focus is to make you happy also. Good relationships are based on give and take. You shouldn't always have to give in to him. You deserve to have your needs considered and met to. So, what if he's not the first man you've been with. Was he a virgin? Find someone who loves you for you and is man enough to accepts that you have a past just like everyone else.
