U should ask him too pick the one he truly love ...but u also have to give him time to think ... n even if things don't work out they are other nice guys in the world .. but hope everything goes fine dear.. (:
Forget about her and find someone else. Just don't make your life complicated. You only live once while love come in your life several times, that why bother to focus on someone who already belong to other.
As him to chose between the two of you who he truly loves. Maybe he isn't sure about what you feel for him and so doesn't want to risk his present relationship. Express your feelings for each other.
You have to decide what you have to do. Ask him what he wants. As he likes you but at the same time he likes her ex. I don't think so that he is serious feelings for you
