So irritated and upset.. Long story!

So my mom married this man out of 'spite' as she says because she just ended a 5 year long relationship with another man because she finally came home to live with her own children.. She married him and she was never faithful. She was out sleeping with another man a few months after they got married. Now this guy my step dad would do anything in the world for her and do anything for us.. I don't understand why she treated him so poorly. We all moved together and got our own place and a little after it was Christmas and after Christmas she kicked him out.. BECAUSE she thought that a guy all the way over in Jamacia was going to move to Canada to be with her LOL!! All my mom cares about is money,that's all that matters to her. She was left 5 years of our life(we still talked through the phone) and she missed 5 of my birthdays. The only time she came home was when her and her other fiancé was in a fight. And she would tell everyone she came home to see us which was bullshit.. Now our step dad had to go live with his parents and when he had no money she didn't want anything to do with him but when he got paid she was right up his ass.. He had a stroke and my mom was all caring and worried about him till she found out he would be okay but she still told him they will get back together and he could come live with us again(she's after told him once before he could move back but then to say no) well after he moved back in a few days later they got into a fight and he accidentally pulled my mom off the couch and she went crazy and started hitting him so he had to defend himself and hold her and push her away and she got my REAL dad to call the cops.. He got charged with assault and she lied about everything! Oh he pushed me down,etc and he didn't. She put a restraining order on him so he couldn't see me or her(he could see my older sister and my younger one that lived with my dad) and then we moved again.. We were planning on moving anyways because it would be cheaper and my step dad got a couch and all that and then she does that.. She makes it so hard for us because we are already struggling like the only reason I have a phone is because my boyfriends parents who pays for my bill.. We started talking to him again(I was going behind her back anyways and seeing him and talking to him) and then she decided that she will drop the charges on him but she haven't did it yet but we all was still around him. I was down to the hospital the other night and my step dads niece saw us with him and called her father and told him that she seen me,my stepdad and my mom together in the hospital and they kicked him out.. He's been staying with us for 2 days but my moms like 'he can't be living here he has to find someone to live with' because she's always talking to a whole bunch of men.. Sorry but she's a whore!! His life wouldn't be so fucked up if she didn't have to fuck it up for him,his parents disowned him and his own brother kicked him out.. He has no one to go too all because of her!! Ugh I'm starting to resent her for what she did and the way she got us living,won't get off her ass and get a job.. I'm sorry this is confusing but I needed this off my chest:(
