His beliefs are his ex

My husband of 3months whom I’ve dated for over 2 years prior does not seem to have his own beliefs about life in general. He’ll say things like we can’t do this and that because it’s a retro grade. I say that’s superstition and ask why he believes in it and he says “my ex taught me about it”....I don’t give a fuck about ur ex.

Well talk about other things like hair and he’ll make comments that black women aways lie about their fake hair being real. I ask if that has been his experience and he says no my brother told me. So I bring the person I am play devils advocate and say well that’s his one time experience, that doesn’t sum up all of us women of color. His response is “my ex told me that all black women lie about their fake hair claiming to real and that they’re jealous of her hair because hers is long and real”. Omg that is so baffling! She does have hair down to her shoulders but wears fake hair all the time and probably claims that it’s her real hair because she already has long hair.Everything that he seems to believe in comes from his ex. I want him to have his own freaking beliefs rather than hers. How do I break that false foundation/beliefs she installed into him? I’d like for him to branch out and figure out life on his own rather than take it from ppl like her. I get that they dated since they were in high school for 5 years but he’s 28 and he needs to grow the fuck up and realize that his ex isn’t god and doesn’t know everything.

** when I do correct him he gets annoyed and says that he’s not going to argue with me, I win he lost”. He’s not that open to realizing what he’s doing. He always seems to think that I don’t get what he’s trying to say.

And I don’t mind extensions or anything either it just bothered me that his ex made fun of those that wore it and claimed it as their real hair when she does the exact same thing
