I am dating two men, guy number 1 is married and we been dating for 4years, and he has been taking good care of me,guy number 2 is very sweet and he loves me but is very abusive, he threatens me all the tym but I love him.. And he is the one I want to break up with, I am so confused and hate myself for so doing!I have tried breaking up with both

OMG,, try hard, break up with both, start a new life. You are in a relation with a married man for 4 years? What were you thinking? Do you expect him to leave his wife for u? If his wife gets to know of you two, he will just break off with u,, that'l hurt more. If he leaves his wife for you, one day, he might leave you for a different woman. How can you trust such a guy who cheats on his wife?
As for the other guy, the best thing to do is break up immediately. Some women tend to adjust to violent abusive life and then they get used to it, and ruin their whole life. Get out of it before its too late. Get out of both the relations before its late.

SilverLining really said it! A married man? For FOUR YEARS? Even if he left his wife for you, things will never be good between you because you'll always be the "other woman"... until he finds another "other woman". If he'll do it with you, he'll do it to you. And there's nothing "sweet" about a man who abuses you. Just the fact that you called him sweet suggests you're already in a downward self-image spiral. Why don't you think you deserve better than a man who's only financially available and one who thinks abuse is a fine way of life?

Run! Get some counseling to get yourself back on a level path. Eventually you'll find someone who makes sense.

What you are doing is totally wrong, you are being a sex toy for a married man ( I hope he is paying you well) does he know about guy 2, does guy 2 know about guy 1.

Abuse is never a answer, so if you have to chose one, do that before you are in the hospital or dead.

The married man gives you nothing but hopefully money and things.

Pick the third choice. A man who isn't married and isn't abusive towards. Someone who treats you right.
