I have this friend and they're in a relationship and I'm really happy for them but they constantly complain about their partner and even then we do lots of things that would be considered romantic or partner like. Im not sure at all how I feel about them, I know though that I'm jealous of their partner and I have no right to. Tbh, I'm FRIENDS with said partner. I can't butt my head in but I know that they think I'm clingy. Both of them. And if I know that, I should now take on a different friend who's expressed their feelings multiple times. BUT NO. I just had to not reciprocate their feelings and continue to gawk at the one who already has a partner. A love. Not me.
