Anyone else the black sheep of their family

It’s so frustrating I could just cry. It’s like no matter what positive things I do with my life my family chooses to look at the negative stuff I did as a teen. I’m 23 now and married with two kids and out on my own. But it’s like anytime I do something good they bring up how I acted in middle school. I mentioned wanting to go back to college next year but I’m the meantime get my CNA license and they started telling me how I woundnt last in that job and would beat up on the residents. All because I acted out in the freaking 8th grade. Like let it go. Then tonight I was at my aunts house and I took my son to wash his hands in the kitchen after playing outdoors and she goes off on me about how I’m the one that started everyone to washing their hands in the kitchen and that it’s nasty and she’s putting an end to it. I mentioned that I didn’t start anything. I grew up doing it at her house and we literally had a bbq a few days ago where everyone (including her and her siblings) were washing their hands in the kitchen. Then she told me to shut up because she wasn’t about to argue with my nappy head ass. Then her grandson started laughing at me. Not to mention he’s 9 and is so disrespectful and she blames it on me. She says that when he was a toddler I’d always grab him when his mom was about to whoop him: number one I don’t remember that and even if that was true how the hell can she connect that to his behavior now. She’s the one that doesn’t discipline him. I know it sounds immature to get upset about it but it’s like my family blames me for everything. My husband is always telling me to just cut them off but it’s my family so not matter how bad they treat me I feel obligated to try and keep in touch. Should I just cut them off and move on??
