Absolutely. My hubby and I hang out with my ex and his wife all the time and yes we enjoy it. I think it comes down to why you split and how both parties dealt with it

Depends if you lost respect for them in the break up. I have one I've been friends with half my life & I married one of his mates but I have another I wouldn't step into a room with because he's a sociopath & I don't trust a word that comes out of his lying mouth. There's no one answer, it depends on the circumstances.

I would say absolutely! I am still friends with my ex, 14 years later. Been with my husband for 12. He knows we're mates, his wife knows we're mates. No issues at all!
