Hi there..new to this site and I need advice. I live with my BF and we are a blended family. Between us we have my bio daugjter and his bio daughter..aged 12 (mine) and 16 (his). The problem is there are diff rules for us all. It is his house and hechas his daughter full time. My daughter I share with her Dad 50/50. Anyway, it seems that more often than not what BF and his daughter say goes whether it be where we eat, weekend plans ect. She blames my own daughter for things she does wrong a LOT. She has issues with taking responsibility. One night she claimed she did dishes the day before and my BF got angry because I contradicted her...she DID NOT, I did them. One thing led to another and I was a lying devil and he took her side believing her lie. Then ger bio mom took exception and now openly hates me for presumably calling her daughter a liar. Fast forward 6 months and my step daughter is on speaker phone with her mom..volume up very loud i couldnt help but hear her mom make negative remarks about me. Again step daughter lied about it said it never happened after i told her dad how unhealthy it was for bio mom to bad mouth me..im honestly just doing the best i can here. Im not out to be wicked as i truly care for step daughter but its very difficult when step daughter is telling lies at my expense. Next thing i know bio mom calls me and screams and yells that i dont matter I am nothing and nobody cares about me. She then proceeds to threaten to come over right then and there to handle it "like women". I dont know about anyone else but that is a direct threat against me and i take it very seriously. So things settle down but now when bio mom comes to get step daughter for her visits she comes INSIDE THE HOUSE. That is all kinds of wrong in my book. Its not my house but i live here and so does my daughter. I feel threatened by her and i dont trust her. I dont see how anyone can say her entering my place of residence is ok..?? Why why why does she even need to come inside? She says nothing to me just walks in hangs out with her daughter and then they leave. I need my BF and SD to understand this isnt something that should be happening. If god forbid we had a physical altercation then what? We are grown adults..we know there will be all sorts of consequences right? Bio Mom drives on a suspended license, had 3 DUIs and frankly has a lot to lose by going to jail. What can i say that will make people mainly bf and SD understand she cant be allowed in our home? SD is going to hate me for it and I dont know what to do. Its difficult enough being a step mom aka GF but SM for lack of better term and now I have to handle a hostile bio mom that wants to beat me up..its almost comical! I feel invisible and diregarded. Like i dont matter and I am only here to shuttle SD feed her and generally be a step mom without any sort of respect. Im sorry for the long vent but I truly am at my wits end.
