So i had this girlfriend, her and i broke up a little more than a week ago. I broke up with her because i was just in a bad spot, things werent going too well between me and life and stuff, and i kind of just made an irrational desicion. So three days later i talked to her and told her i wanted her back. That i made a wrong desicion. So she said you "you dont want me back" and i asked why. And she told me she cheated on me (like all the way) with this guy about a month and a half ago, and we were still dating at that time. So yeah cheating is all bad and stuff, and that wasnt the first time. She cheated on me two months into our relationship with this other guy. So thats twice she did that to me. But i dont seem to be angry... i mean, when she told me i thought i would be. but im not. after the first time she told me i was really upset but i forgave her... so she blew her second chance i guess. But i cant help but want to forgive her for this time too, im not gullible, im a strong person. She says stuff like that i make hger happy and all these things, she doesnt have an ideal life, shes got terrible parents and she was 'blackmailed' in a loose sense the first time she cheated on me. And she asks for my forgiveness every single day, she says she now keeps a note in her pocket, a note too herself that says "you promised".. and she says that i should forgive her because love forgives.
So any help? im trying to decode if this is a true sincere thing and i should restore my trust in her and take her back, or if this is all just something to try and keep me with her...

Dude...end it with her like as soon as possible. The routine of her cheating is just going to keep going, thats an unhealthy relationship. I do believe you should still forgive her but cheating isn't right. You wouldnt want to get hurt over and over again by her cheating on you again, would you? makes you feel like crap...and dont feel guilt either..i know it will be sad to breakup with her but its best for you and its what you deserve.
