is my mother jealous of me?

Me and my mother never had the best relationship but I was a good kid. Never got into fights, drugs, and I took care of myself since I could;never really asked her for anything. I moved out of state and hardly talked to her my life was very positive. My oldest sister passed away so I moved back home. Ever since life has been hell. My mothers boyfriend seen me for the first time and all he' did was talk about how pretty I was, I was uncomfortable and I can tell she was pissed. However this happend numerous times with numerous men and some how I get blamed for it. If I say anything to her it's like she just wants to jump on me. I just feel like she hates me. I can never do anything right. When I get dress I watch her admire me and then get disgusted quickly. Her self esteem has always been low I say it's due to my father putting her down for years. It really hurts me that she's never proud of me. I have two other sisters who are gorgeous way more prettier then me and she doesn't act like that to them. I did once hear her say I'll never get a man they always want my daughters. I dont have children and I'm trying. I could never treat my kid the way she treats me. All I see is envy. I hope she finds real pure happiness because until then I think our relationship will suffer.
