got blamed for the breakup of two girls

ok I am not going to you real names me gay girl-robyn straight girl- erin

ok so robyn is gay and she meet erin erin was straight but feel in love with with robyn well they were together for 4, going on five years.

well Erin has cheated on Robyn 6 times (with a guy) she went to miami got the hurricane relief and left robyn for a guy and stayed down there all summer and left robyn with her two kids and then robyn took her back after that too .. well I moved up here when I turned 18 to find my biological family and went to work at mcdonalds were I meet robyn and we have been friends since then (which was in feb.) and after me and my mom got into I got a back pack and walked from pinson to cullman and finally called a friend to come get me because I could not walk any more and then I ended up moving in with robyn and Erin and her two kids . now as I was staying there I could see the way erin treated robyn especially since erin dont have any highschool education or a ged and can not support her self . robyn pays all her bills and everything and all erin does is sit at home and treat her like shit .well finally it just kept piling up on robyn and she just had enough .. then erin’s sister comes in to town and htat did not make anything better

as her sister was there she kept putting things in erin’s head like me and robyn were “doing stuff” and then my own friend heather tells them we were doing stuff and robyn’s friend anna tells erin the same thing so now erin thinks were are doing things and were are not so it finally just blew up and robyn decided she was leaving then it was phone call after phone call about how I am a bitch and I caused this I stole here and calling robyn leaving mean messages and gettign the kids to call saying why did you leave us like our daddy left us and when are you coming back those kids are like robyn’s kids too and she loves them like her own so she is completly torn up right now and I dont know what to do we are getting an aprtment toghether and we are not together I am straight we are just friends even though no one believes it but oh well please help what can I do for her to get her through this ????
