My household ruined my mindset

I’m not sure what to do or how to stop this way of thinking. My parents never really care about much that goes on in my life. For example, I have a boyfriend and I want to be able to talk to my parents about him and I do, but the problem is that they don’t even pretend to care. They don’t ask me any questions and when I’m telling them something they’re either so rude and turn it into something negative or they just don’t care.

Like I told my mom that he bought me something very nice meaningful and she said “why is he spending so much? he has a problem controlling his money” And it wasn’t even expensive… less than $100 and it was a good deal for what it was. Meanwhile in my other relationship, where the guy didn’t spend a penny on me, she would tell me he’s a cheap man who wasn’t raised right , etc. So do you want a man to spend money on me or not?

Last night I told my dad that my boyfriend wants to have a drink with him and spend time with him, my mom quickly goes “Why do you always pick shit men?” I was confused and asked what she meant and she said “He’s an alcoholic” I was like ???? Just completely confused.

If I, not my boyfriend. do something wrong like for example lose my jacket somewhere, my mom will get mad and she’ll be saying something bad about my boyfriend. Completely unrelated to him, but she’ll do it.

They wonder why they’ve never met anybody I’ve dated and this is honestly why. My boyfriend wants to meet them, but I’m scared of what they’ll say to him. They always tell me I can do better than what I have, when I have someone better, it’s still a problem. They’ve ruined my mindset because now when I’m with someone, I think “I can definitely do better” constantly thinking of finding someone “better”. I’m fighting this thought so much right now, because I know my man is the best to me. I love him so much but they’re constantly trying to make me think negative. The examples I gave are just a few examples of my relationship now. This has been going on for years and I feel like it’s been the reason I’ve never been happy with the men I was with. I just want to be able to talk to my family about things. Any advice?
