Well you said a few things that seem like in your mind you already know what you have to do. You say you can't trust him, that he lies about small things, I agree that you moved in quickly and understand it was because more than likely like me you needed a place, an you were COMFORTABLE with him. Here are my thoughts, your 20 yrs old baby girl you have no kids I assume.. And you seem to stay with this guy not out of love but because you feel safe. You have a home, food, and someone to come home too. The bad thing is I think you are selling yourself short. You want him to be something I'm pretty sure you know he isn't going to be. Not because he doesn't want to but because he can't. His lying is a way to make himself feel better, more than likely he believes them himself because he is insecure an has self esteem issues. And not to be rude but I think you are insecure in yourself as well. I am too. The last thing you need to do is stay with this guy just because you have a past.. Wouldn't you like to have a better brighter future?? One with someone you trust, love, and most of all Respect as a man? You need to ask yourself this. Do I want my future to be with him and be married wondering if I had done things differently would I be happy with someone I trust, or would I still sit and have to sort thru the stories to get the truth. I may not have helped you too much here, but I hope I gave you some things to think about. Your young just starting life and trust me from my own exp. There are people in this world who will be good to you, they will be honest an be there when you need them. Take time to think about the type of person you are and the type of person you want to be. When you are serious about another person they should bring out the good things you like about yourself. Like a nice pair of Heels with a matching handbag, they just fit and work well together. Good luck to you!
