Am I Wrong?

Ladies my SO uncle is a drunk and druggie he literally does drugs and drinks everyday outside his mom's house. We are ttc at the moment i told my SO once I have our baby I want nothing to do with his uncle. His uncle hates me because my so and I started dating at 16 and 17 and now we are 19 and 20 got married at 18 and 19. He thinks that I robbed his man hood or some shit. He was saying oh he's still young he should be out partying and living life. Last time I went over to my so grandma's house his uncle stays with his mom (37). He literally would mean mug me, talk shit when he can to me, tell my so to leave me and I'm lazy. He's a druggie, drunk and a bitch in my so opinion and mine. Is it wrong I don't want him around our future kids or even to see our kod.?
