Situationship??

So I'm not too familiar with this app and new, but I've been having this issue lately with on of my friends, lets call her Ava, who I started to like for a few months now but she's not exactly the attractive type. And by that I mean she has alot of red flags. And she was in a toxic relationship with her boyfriend until they broke up and got back together, which was what I heard from her last before I stopped being around her. And idk if I should really consider her as even my friend anymore if I can't really see being in a relationship with her because she's so emotionally unstable. I thought she was cool in like an edgy mysterious way but now I see that she is kind of a social reject. Not to be mean or anything but her personality isn't the best. Maybe I just liked her style, but now that I see her everyday in class I just try my best to not look at her or pay her any attention. Was this the right choice or not?? Because now, I decided to hang more around these 2 other people, Jayce and Melanie, who were also close to Avery before they stopped being friends with her too. And Melanie is super nice to me but Jayce is more quiet. I feel better with them anyways. When I was with Ava and this other girl, Ray, who I sat with too, they were always on their phones or didn't talk. And always never responded or flaked out on plans when I tried to invite them somewhere twice. So whatever. Ray can stay with Ava, but I'm not going too. What do you guys think cuz I didn't want to stay with Ava or else my feelings for her wouldn't go away. Does anyone think that Jayce and Melanie like me now that they see I'm kind of wanting to be their friends instead??
