Do some people never grow up?

35f here. I met this girl who I was friends with when we were both 26, she was from Russia , I am from India , we met in NYC and we hung out a lot, went out to bars etc, did things young people do. She was always the type who would go for abusive or loser guys and fall for them and make it a relationship, high tolerance for their BS and cling onto them and try to make it work, but eventually it wouldn’t . I also fell for unworthy guys sometimes (they were still nowhere as bad as the guys she fell for). When I turned 29 I fell for a good supportive very loving guy and we are still together, married now. She’s 36 now , she’s also married but fell for an emotionally abusive guy and was crazy in love with him and she married him too and on and off it’s a nightmare with him but she still puts up with it and will run back to him again and again. I tried putting some sense into her but it was useless , but I took my distance from her, because of our major personality differences and growing incompatibility . She was exactly the same when I met her at 26 when she was 35 and never emotionally grew up. Do some people not change ever or it takes a lot longer for some to realize?
