I would date anyone that i was mutually attracted to, have an interest with.

I am the best friend of my ex. I would date myself, but I would deeply regret it.

my ex didn’t have close friends, which really should have been a red flag.

Could only decide on a case by case basis. There are a lot of factors to consider.

I had a chance to but I didn't, the friend asked me to come hang out with her, not that I'm completely against it, it was more like our friend circle was tight and it would have taken 13 milliseconds to get back to my ex and I wasn't on board with THAT shitshow

It would be weird but if I'm into them I'll embrace the weirdness.

Yes. Why not?

No, unless my ex is evil. I don't want to hurt them.

Sure if I liked them and they lived here or were willing to move or visit here
