one thing u just have to think is she worthty to be love or is it worth fighting for your relationship with her...and to think if she can move on u can do it also your a men and she is a lady so better prove to her that u can stand on your our own without her in your life...or if you choose to be like that do u think it will help your healthy life...go out and have fun go with your friends start hanging out with them again...dont just focus yourself on her...and when u had a chance to move on with your life try not to give all the love please keep something for yourself you have to love yourself first in that way u will know if someone is abusing or just using u...u dont have to feel guilty on cheating with her i think u can only feel that if she stays with u and love u and never cheated on u even u cheated her i think that way i can understand u but if she can cheat on u once she can do it again and again ...ur a men...so be a men and prove to yourself that u can move on and be happy again with your life ok goodluck take good care of yourself and relax stay cool...its not yet the end of the world so keep on smiling and pray ask your god what to do and your god will guide you....
