My mom and I haven't had the closest of relationships in over 5 years, which all started with her kicking me out and calling the cops on me at 15 (solely for me not talking to her - I no longer saw any point in arguing with her as whether I argued with her or not, I always got in trouble). She lied to the cops, our church, family, and family friends about me abusing her and my baby brother, me being crazy (by talking to myself - a normal thing for literally everyone), and all in all tried to make me out to be this terrible daughter, sister, and person all around.
I found all of this hard to believe as when I was still in high school, she kind of parentified me by making me drop off and pick up my brother to/from preschool (before and after I had school), I did grocery shopping, cooked dinner, cleaned around the house, bathed my brother, made sure my grandmother (who had dementia) was well taken care of, and always made sure everyone was okay meanwhile my mom was "fixing up" my grandmother's old house for us to move into (as we were being evicted after my mom tried to take our landlord to court over a refrigerator issue). Needn't I mention I felt all she and her friend really did was clean up the place some and install some new lights in the downstairs kitchen (which we didn't even use). I have a younger sister, but she wasn't the type to help out, which I can understand because neither of us we supposed to be in that position.
Longer story short, I stopped officially living with her when I was 17 before I graduated HS. I didn't want to invite her to my graduation, but did so begrudgingly as coerced by a close relative. Created a boundary with her that I don't like being touched by people I'm not on good terms with, which she constantly ignored when I tried to put my siblings between us, and she forced herself next to me and her arm around me.
Years later, I can be cordial with her, but still tried to keep her at arm's length (which I failed at numerous times after feeling bad I was going excluding my only mother/parent). She came with me to doctor's appointments my fiance couldn't make, gave me money for a car upgrade, offered to throw me a baby shower, and some more.
One night I called her just to check in on her. I don't know if she was drunk/high/etc., but she began rambling to me about things she said I did/said to her (which I never have; had to have been confusing me for my sister who had actually mistreated her). I took notes and confronted her about it about a week later after I had time to evaluate my feelings and whether I was just being hormonal and unreasonable. She basically blew up, started crying (a norm for her when confronted about her behavior/actions/words towards others), and again tried to accuse me of things I literally never did/said to her. We hadn't spoken cordially since.
I recently gave birth to my first baby. Throughout my pregnancy, my mom stressed me out, tried to lie to people about be saying I don't want her in my life, cursed me out via text, tried to down talk me at my own baby shower (that I ended up having to throw for myself after we had another falling out) to my fiance and future in-laws. She asked if she could come to the hospital while I was in labor, I had it so she came to visit only after my daughter was born. Despite us not talking, I made plans for her to come visit TWICE, but with restrictions since she wanted to bring my brother, but I told her he couldn't come if he was sick. She blew up again, told people I was keeping her from seeing her granddaughter, and might have to take me to court for "grandparent visitation rights".
WIBU to keep her from my kid(s) in the long-run?
