oh girl!!!!! this guy is not worth all the effort you are doing trying to keep him. He already said he doesn't trust you and that's not going to change because of the circumstances, but I think he's using that against you to get what he wants which is wrong. Yes you did what you did and you regret, we all make mistakes the key is to learn from them and not do it again. You desperately need to move on from this relationship, and move on. It will be hard but you deserve to be with someone that will treat you right and respect you!!!
