Meh been there done that. Too much responsibility.
Nah, even if I wasn't married, I have chickens. They think I'm the bee's knees.
When those others I'm sorting by "favoritism toward me" are not of a certain minimum caliber, yes. Lowering my standards just to feel accepted by those I don't feel inspired by in any way? Nah. I'm good making my own joy and finding new experiences (and friends). The punters can keep their shitty views & vacuous lives, if it makes them happy. Not my monkey, not my circus.
Just let those relationships die? I don't mean if you're not someone's precious one and only to let them go, but if they're giving you the impression that you're a "backup," just stop starting the conversation.
It may not feel good at first, but I think it's a step in valuing yourself and your time. I did that and I lost every high school and college friend because I stopped being the one to ask them to hang out, play games, etc. I stopped watching the invites "miss" me and what have you. I realized I was giving much more thought about people who didn't remember I existed.
Being alone is not the worse thing. Being alone with a room full of "friends" is much worse (imo)
I had this realization a few months ago and got pretty sad about it. But now I realize that I have complete and total freedom to just do whatever I want because no one gives af about me. Lay on the couch all day and binge soap operas? Cozy. Make a mistake? No one sees it. Move to another country? Why not. I don't have to answer to anyone and it's amazing.
