Dont know what to do anymore.

Have you ever just tried your damnest and did the best you could for someone. And it was never good enough. They just put you down so much that you get yourself believe that you are everything that person says you are. But you cant walk away because you love that person so much. No matter how much they take they ring off and tell you how much they hate you. They cheat on you. And talk to so many girl. But you still stay... No matter how many times they lookright at you and tell you how bad there want to fu*k some girl just because they have a big butt. How much they call you fat and shit... I really dont know what to do. When i took my vows i truly meant them. I just not sure howmuch more i can take.
