Why do people

Involved with my ex who treated me like shit and used me and put his bratty half Japanese ex fucking still bother with me for? She fucking used him for money and the both of them tried to instigate shit, so I ran off. Should I talk to him anymore if after we broke up he fucking had her over and they drank beer and hs took smutty pictures of her in his room in a thong? I ended up lying to him and running away to NY for several months before going back to school. I hate how I always fucking put up with this shit. His ex Jade always demanded the fucking Queen treatment, but when it came to me, I fucking ran off, lost weight, didn't talk to anyone, deleted my Facebook, changed my phone and number and look what happened? I always came second to Jade, she could try to make me suicidal, make comments about how she wanted to fuck my abusive ex, sleep in the bed with my ex boyfriend, take drugs with him late out night or go out with him to clubs when we dated and she went to his fucking family birthday dinner. So what does anyone want from me? I want to run away to college ALONE because I know that I'll never end up happy like the other girls. His ex girlfriend was engaged to someone else that she had been seeing for at least six months, and she was telling my ex when I dated him that she loved him and got angry when he wouldn't say it back and then I found her naked pics with a bar over her tits on his computer and their pictures when they dated as teens. He'd put me down for going to Disneyland but he'd sing her praises about going to Orlando Studios, he wouldn't help me with my hw if I asked, but he'd help her with her German class menu and he'd have her over late at night, drinking Amaretto and I'm just done. I don't think I can ever go back because I'm scared of my exes ex girlfriend. She'd call me fat/cunt/bitch/asshole/fuck you and make fun of me and he wouldn't defend me and say I deserved it and that she had every reason to call me an asshole. Even when I was skinny, she'd attack me for no reason. So I fucking ran the hell off. She got jealous of her other exes new girlfriend Leslie and then she fucking would put my ex boyfriend into a bad position and fucking badmouth his brother and encourage me to just disrespect his mom and then my ex would tell me that I reminded him of his brother. That's why I ran off. I stopped eating because I was so fucking stressed out and everyone else said she was in the wrong yet he wasn't over her and as soon as I got skinny he was back up my ass again. But I wasn't allowed to insult her or fight her or instigate shit with her. The worst thing I did was forward the texts she sent to my ex to the guy she was engaged to and told him to tell her to handle it and leave us alone! My exes mom said he didn't respect me and it would get worse if I got married, especially since he fucked with drugs, so why does anyone want me to deal with him anymore?
