Why doesn’t my cousin like me? What did I do wrong?

I have a female cousin the same age as me who seems to can’t stand me and it’s been this way since childhood. She’s always been rude, dismissive and shady towards me every time I would see her. Now that we’re adults we don’t speak and it’s because she’s made it clear she doesn’t care for me, but why? I am an almost college graduate and she’s now on her 4th baby and 2nd baby father. She’s made snarky comments about my college career and she’s extremely fake. The only time she came around me after the past 8 years or so was to try and sell stolen clothing items to me. After I politely declined (because I don’t buy stolen shit) she basically gave me her ass to kiss and told me to kick rocks. I never understood her deal with me and I never got a chance to ask. I text her to see how her children were and she never responded to my message. I just want to know did I do something wrong? We didn’t grow up together. I’m from a different state than she is but everytime I would come to visit relatives she would always count me out or act as if I wasn’t there or didn’t matter. What do you suggest I do because it seems as though blood isn’t always thicker than water, and she doesn’t treat me like family at all? I’m a really chill and cool person so I don’t understand what I did if anything at all. It just kind of sucks because I don’t have any female cousins my age so it’s confusing and unnecessary when she acts like that. Especially since we barely been around each other in our lives.
