I’m starting to strongly dislike my mom, this is just a vent

She wasn’t the greatest mother, and now that I’m older I’m starting to think she really wasn’t a good mother at all. Idk where to start but to sum her up, my mom is that evil MIL. lol So my mom always had some smart shit to say, or always wanted to brag or be that person to say “I told you” And most of the time growing up even as an adult I used to just let her say whatever. But now I don’t especially when it comes to my kids. However we always did but heads, it be times where I wouldn’t speak to her and then something happened& so I didn’t speak nor see her for years that she didn’t get to meet my first until she turned 2 years old. Sometimes I try to have the sympathy for her that she’s alone and she just needs to say shit to make herself feel better but lately when she say some dumb or unnecessary stuff to me or about my kids I instantly fight back. And thennn she’s not even a good grandmother she expects me to always bring my kids to her but can never come to us & she’s not even that old. In my culture we do stick with our parents & help them, so it makes me feel guilty about distancing myself from her, again. But she’s very negative & let’s say toxic. I ignore her most of the time when in front of my kids but when she say something rude to my kids I without hesitation nor thinking say something back to her. And she is the type to get extremely mad and start to wish bad upon someone or call my sister to talk about me say this and that. This is just a vent but do any of u have a parent like this and how r u dealing with them. I sometimes want to cut her off but same time I don’t. I grew up without a father but I’ve noticed that I do look for a mother’s comfort in older women that I cross paths with, whether it’s a boss/co-worker or instructor of some sort.
