Is OTHER wrong in the post ? POST : Throwaway because I don't want to risk getting identified by people i know who use reddit. Last year my dad discovered that mom had been cheating on him with one of his close friends. The only reason he found out is because his friend's wife snooped through her husband's phone and found old convos between him and my mom. my dad was hurt and devastated like i'd never seen before and that affected me deeply. she had been cheating for almost a year apparently and in the months leading up to them being found out my dad's friend was trying to break the affair off. This explained a lot of things that were going on at home. My mom had been acting very aggressive and was extremely unpleasant to be around during this time. she said some very hurtful things to me due to my appearance (i am overweight), me going to community college because i couldn't get into a decent uni and my lack of friends/social life. 

My dad kicked her out of the house not long after the initial shitstorm. Mom went to live with my aunt and she's been there ever since, but yesterday she called dad and told him that she needed a place to stay because her sister was going to move and wants mom to get her own place. She said that she can't afford an apartment right now and that she wanted to come live with us again. My dad told me right off the bat that he had no desire to live with mom again but that he wouldn't keep us separated if i wanted her with us again. 

I haven't spoken to my mom since the day she moved out. She sends me texts every now and then but they're always ridiculously long and I rarely read them and I've only replied a few times. To be honest I am still very hurt due to how she treated dad and how much she hurt him by betraying his trust. I am still very angry at how she took it out on me and dad when her affair was going sour. I am still very angry at how depressed and anxious i felt because i thought that there was something wrong with me, that i was making her unhappy and that's why she was constantly attacking me and putting me down. i don't think i can ever forgive her for the way she treated us because the man she was fucking  wanted to end things and she didn't.

i told dad right away that i didn't want her anywhere near the house again. that i wasn't ready to be around her again. 

but last night i had a lot of trouble sleeping. i feel guilty and petty for saying no, and it makes me fucking angry that i even feel this way because i truly do not want to see her again. i hate feeling responsible for what happens to her. I am dreading having to work today while feeling like this. 

do you think i am taking things too far by telling dad not to let her live here again?
