I want to leave my girlfriend, but the thought of her moving on with another guy is destroying me.
Me(22) my gf (21) are on edge of breakup , she have cheated me when we were not taking by saying i love you to her senior in her college ( he rejected her then but now he wants her ) she also had male bestfriend whom she made when we were not talking , i want to breakup with her but i think after breakup she will go back to that senior and they will be in relationship and i dont want to let this happens, neither i want to marry her or stay with her , i am in dilemma what to do , two options , breakup will hurt more bcoz of she with another man ,i cant digest but on other side i can't marry, if i breakup my mind will be haunted by thoughts like they will be doing these and that.... should i keep her bcoz she done this when i was not here , if i am available to her then she will never do this , aslo i will tell her she should never do this again , bcoz she just proposed and she is not touched by anyone yet ,she is still pure and mine ,or should i let her go and dont care what she will do , what to do ???
