Is is possible for someone to become friends with their ex's new spouse?

Not exactly the same situation, but my ex girlfriend is on friendly terms with my fiancée. It's possible.

I used to think so. But i was wrong

yes maam!😼

I prefer my ex's x over my ex

Please no.

Some people do but I think its a little too much for me but especially if kids are involved then yes.
Or maybe if I became utterly repulsed by my ex then it would be easier for some reason.
