I need some advice on what to do about a band I'm in. Help?

So, me and a friend of mine have been wanting to start a band for a while. We met this guy who sings (we both play guitar) and we started practicing with him. My buddy said he didn't wanna practice with him bc he didn't really like him anymore and thought he was kinda weird. I was like aight dude that's cool, I decided to keep practicing with him bc its hard to find my people in my area who like rock music, well now I don't really like him any more either. I only practiced with him once since my friend quit practicing w/ us and he is really weird and seems to be focused more on drinking then making music. My buddy just quit texting him back abt practicing and he left him alone, so is that what I should do? That's what I've been doing.. he text me twice this weekend, but I just didn't text back. Now this other band is looking for a guitarist and I'm thinking about trying out bc it is more of the genre I want to do anyway (pop punk/metalcore). But I overthink things so I keep having anxiety that i'm gonna get in this band and they are gonna know the guy that I used to practice with and started ignoring and its gonna screw things up. Please help me figure out what to do. I keep worrying about it.
