Advice on sister’s bf

I don’t want my sister’s bf around my baby or integrated with my family. Am I wrong? For a bit of background… My younger sisters bf is a guy I was friends with in college. She moved to a new state after knowing him for 3 months. In those 3 months, she lied multiple times to me about who she was with/where she was. After moving to the same state as him, she drove over an hour multiple times a week to go stay at his house and would lie about that too. What makes this the worst is I was pregnant and living in the same state that she moved to. She only saw me once during my entire pregnancy because she was too busy going to visit her bf and hanging out with his friends. She took up his hobbies, adjusted to his life, and has very few friends of her own. I’m not over the amount of times she lied to me about who she was with (despite us having multiple conversations). I’m not okay with her following him around and still not having a job at 26 years old. And I’m still not over the fact that she and her bf basically ignored me and my husband during my entire pregnancy and never spent time with us. They also had the audacity to get mad that we stopped inviting them over when I started to get sick during pregnancy. Now, unfortunately, they’re still together. Coming up on 1 year. Is it wrong of me to still not want the guy around my 2 mo baby? I don’t see him in my sisters future and I don’t want my baby around people who aren’t family/close friends. I don’t want to come off as holding a grudge on how the 2 of them behaved but I can’t help the amount of anxiety and stress they bring me.
