Suspicious Behavior...Should i leave her?

I met this girl while she was pregnant with her first child after being a butch for many years. We have raised her son together for 19 months now.Within this time she has cheated on me with 2 anonymus men () and the other being the father of her son. She also cheated on me with two girls (kissing).. I hav cheated on her techniquely while we were broken up 2x with my ex boyfriend. and since then i hav understood that i will hav to earn my trust bck but to her she just wants me to trust her like as if i was the only one who did wrng cuz i slept wit my ex (bfre me and her were even a couple) but i was talkn to her and we had already kissed. she says tht made her very angry n so she did all tht she did to me cuz of it. It has now been well over a year since the cheatings. She is now living at her sons dads moms house until she gets housing. she never introduced me to his family as her girlfriend which has me on edge cuz her son calls me mommy and i am afraid he will be confused later as of why his mommy isnt allowed there at his grandmas and why she dsnt like me? she is real religious ( A jihovah ) altho she stil curses and talks about ppl behind their back.. which i thnk is rediculous and so i dnt feel i shld totally respect the woman just for being a jihovah.. anyways there are pics of the dad of her son tht i askd her to put away while im there. she refuses. Its like if u care about my feelings n u want me to feel comfortable visiting u here then do u part right? . Im not askn her to brake them.. just put tht one pic in another room . Also if the family were to come and visit she says i would hav to hide! I am practically in hiding already since they dont kno me as her girlfriend.. Another issue is there is a friend she has known awhile. they used to date tho she Claims she has no interests in him. She makes it seem to everyone tht she is annoyed tht he comes over constantly. literally 3 to 4 times a day sometimes at All hours!! and each time she hides n tells someone to tell him she is asleep or not there.. If she is so annoyed with him then she shld say "hey im busy" right? i understand he is the only one tht will fix her car for cheap n she cant lose tht in her financial situation but still! I shldnt hav to put up wit it right? He lives at her dads where she hardly invites me to anymore cuz she knows i dont like him. When she does want to talk to him she goes outside with him for an hour or more. Literally what she does when he gets there is she walks outside without sayin anythin to me while leaving me to watch a movie we planned to watch together all by myslf! She tries to get me to believe tht since i hav changed my mind on her so many times tht she is now fed up with changing for me.. It took her many mths to stop talkn to the girls she kissed whereas it took me not even an hr to call my ex n tell him not to call me anymore.. i also had to stop talkin to my guy friends cuz they were flirting wit me.. i did it quick style but she claims i dnt do anythin for her HA! My goal is to get my heart to understand wat my mind already knows...
