I know it will be hard but look at this as if you had a younger sister telling you all of these things. You need to see that this man is not good for you. For many of us, we cling on to people who will tear us down even more, we think we can not live without them. I don't know why but it just works that way. Once you free yourself of him in your mind and view it as a good thing, you will be able to happily move on. It's hard but you wouldn't want someone you love in a relationship like this, so love yourself and don't put yourself in it. I will be thinking of you and wishing you all the best on this.
