My mom has nobody and I'm being guilted

I had a really rough childhood growing up. I didn't have my dad because he died in the military so I never got to know him and my mom was a mess. Recently her caseworker reached out to me . Turns out my mom has been homeless sleeping on the streets and she was taken into a women's shelter. She had the caseworker call me and the caseworker said my mom has been asking for me. Crying at night for me. That my mom was diagnosed with bipolar disorder and wasn't well.

That makes sense since I'm bipolar but I never did any of the things she did. My mom tried to be my "sister" instead of my mom. And not a good big sister. A bully big sister. She put me down a lot growing up. She did keep a roof over my head. Fed me. Clothe me. I get it. But she made my life so hard. My mom fucked up my life with her actions. She used to get jealous of me because I've always been pretty and boys would hit on me. So she would flirt with boys I would bring over and this started when I was 12. She would flirt with my 12 year old friend that I liked. When he was 15 she was pressuring my boyfriend to kiss her for fun. She had sex with a guy I liked in our home while I was there. He was 18 so it wasn't illegal. Just weird. But one of my male friends told his mom that my mom cornered him in the bathroom and tried to give him oral and have sex with him. He was 16. His mom called the police. That whole thing ruined my life because my mom was saying it was consensual. Not an attempted rape because 16 was age of consent there. She was found not guilty for lack of evidence but everyone already deemed her a predator which effected my life. I couldn't have friends over anymore and nobody would be around me. It was for the best because my mom spent years sexually harassing my friends. I was also raped by her boyfriend when I was 10 and it was so violent I can't have kids.

I left home and I'm happy. I have an amazing husband and 3 step kids. I told this caseworker a lot of this and her reply was "Well your mom ok wasn't well so it wasn't her fault." It became clear this caseworker is actually trying to get me to take myom because she can't stay in the women's shelter forever. She's saying myol really misses me. She has nowhere else to go. I feel guilty but I don't want her anywhere near me. I hate that woman and I'll never forgive all that bullshit childhood i had. And I don't want to hear that forgiveness will set you free b.s. I became free when I left. I don't forgive her and I'm not living in anger. I'm living in peace with my husband and step kids. So please don't come at me saying I need to forgive because I don't. I'm happy in life. Another thing is I have underage step sons and she's already proven to be super inappropriate with underage boys. I will not put them in that position. This caseworker has been guilting me about how she has no one and she need me. I feel so emotionally drained by her
