Need advice. Please help

So my childhood wasn't the best I'll try and make this short. My older brother use to beat me up all the time. My mom never did anything about it and he just got away with it all the time. Our father ended up dying and it got worse. My older sister found it funny to inflict emotional turmoil on me. I sneezed once and she slapped me so hard it tore my ear drum and I've had a ringing in my ear since.

They made fun of me all the time so I got bullied at school and home. I have physical and emotional scars because of them. For the longest time I thought I was stupid because of them.

Now the issue. Since breaking away from my family I've been so happy and have felt free from the burden of having to deal with them. My mother has been hounding me to reconnect. Saying stuff like they need me and she wants her family back together and forgive them if not for me than for her....

First off I'm not close to my mom. I don't really like talking to her to much I've only called her 2 times this yr so far and each conversation consistented of her asking me to forgive my siblings.

I have made it clear I don't want jack to do with them and I want her to stop bugging me about it and if she can respect my wishes she will get the same treatment. I fully believe that family is formed by choice not blood. Now she wants to know if she can take my kids off my hands for a few hours so they can meet my sister. She thinks of it as a small step to her goal... On one hand I wouldn't mind getting rid of the kids so I can get alone time with my husband which we haven't had in months. On the other I don't want my siblings around my family period and I don't want my mom thinking it's a step to reconnecting. I'm conflicted. What would you guys do? I just wish she would stop putting this crap on my plate. Please help.
