what should i do

If she cheated on you many times as you said, maybe she doesn't deserve your love. Have you talked to her why she cheats? And my question to you is, why do you put up with it?

Sweet heart there are plenty of fish in the sea and take this from a girl who dated a guy for 8 years and flip flopped between breaking up with him to date other people (not cheating but bad) and getting back with him because he was there when I was lonely and convient. I know that sounds horrible but in my mind at the time it made sense. She's just using you. She might not even know it. Leave that girl!

Oh my, stop the cycle and get out. Your girlfriend won't respect you so you need to respect yourself and leave her. Her constant dis-respect for you has beaten down your self-esteem. Her cycle of cheating will not end until she grows up. You, on the other hand, need to heal yourself and get your self-esteem back.

You really need to leave and be serious about it. Then if after maybe a couple of weeks or months you want to try again, you should really have a talk with her prior to any future commitments with this person. It's obvious she doesen't respect herself and you and this is someone you really don't want to be with unless they truly change.

forgive her one more time..

Its become a habitual response for her to cheat. She knows you will forgive her no matter what she does. You have 2 choices, either accept that she cheats, knowing she comes back to you after each indiscretion OR let her go- FOR GOOD! They are both painful but no one should be a doormat, you should be able to trust the person your with.

Once or twice is enough. Forget her, for you are just wasting your time and efforts to such unworthy partner. Live your life and enjoy great things around you. Do it before you got yourself killed by your emotions or depressions. Have her learn something that she shouldn't hurt a guy like you. It's normal to be hurt but don't get yourself too much because of her. You still have friends and family and you will still meet new people who would care for you.

if you love each other,you should forgive her.and i think it must have some reason that she cheat you.

Hi decade1900, If you are truly in love with her, Let her know how much you feel when she hurts or cheats you, If she doesn't care abot your feelsings, Why you should care about that kind of girl...? It's illogical, Just feel pity for her and leave her...! She's not worth of your Love...!
