Ok I'm gonna get right into it so I met this girl in January of 2014 and we talked for a while go to know each other and we fell in love so then we got together a few months later July 11th 2014 we had a normal relationship for a while we were both happy then things got a little out of hand and I tried to break up with her she then threatened to kill her self so I didn't leave here then this cycled I tried to break up with her then she threatened to kill herself I didn't believe her at times and it got to a point where she proved she was being serious she cut her wrists in front of me and forced me to watch it she wouldn't let me close my eyes or look away so that's when I realized she was crazy lol (I know it's not a laughing matter) so then I made her get help and she did she went to the doctor and got meds and stuff and surprisingly with time she got better and then I screwed up and cheated on her and she found out and broke up with me but then I fought really hard to get her back and I did then we were doing good for a few months and then she did the same to me she cheated on me and then I fought for her and won her over again from that point we called it even we obviously didn't trust each other but we stould together and from the point she cheated on me to October 18th of this year so from April 16th to October 18th we argued every single day non stop (I'm not exaggerating either we literally argued everyday) so this is obviously unhealthy she then cheated on me again on September 24th of this year and that's when it was the last draw we were completely done (or so I thought) so we didn't talk obviously from September when she got her new bf that she cheated on me with till last Thursday the 15th of December she messaged me out of the blue saying she missed me and gave me a big story about how she's sorry and wants to make things work so I've been talking to her for the passed few days and I realized she seems like she changed but I will never trust this girl again she trying to get back with me but now I just can't trust her I constantly feel like she is talking to another guy and lately I feel like she's just being nice until I decide to get back with her and that's when she will be the same old person she was before so I was wondering what should I do about this should I walk away or should I try again for those of you who ready this give me a reason don't just say walk away and don't just say stay with her thanks for reading and thanks in advance to those who help.
