My relationship sucks now.

Im tired of my relationship now. I feel there's no trust and the only reason im still around is because the sex is crazy...seriously. Like we argue everyday and im really just fed up. i mean after all the shit weve been through, youd think we would have learn, but this chick is still mad over old shit...I could have sworn not even 2 weeks ago, we called a truce and was going to start over but I guess not...Its to the point to where I think letting all of these girls go was the dumbest thing Ive ever done. I mean right now, I could break up with her right now, and wouldnt give a fuck!!! Id just go on and fuck somebody else the next day....I feel like im the only one sacrificing: time with my fam, people who actually call me and want to chill, girls, my sanity. I mean the only thing keeping me from cheating right now is...well idk? If this is what we call love now a days, id rather be alone. She keeps trying to make it seem like shes getting mad because I didnt call her but its her own insecurties thats ruining our relationship. Im grown and if she thinks im going to call her at night to check in and I dont have to check in with my parents, when she can call me if it was that major, shes fucking crazy. Pay a few bills and take me shopping every week and well have something to talk about. But until then, get your shit together,and stop worrying about silly 3rd grade shit and we wouldnt be having these problems!
