Is your bf or SO still in contact or friends with EX(s)

& how do you feel about it or how would you feel about it?

Currently my situation & it drives me insane. They still hang out to grab drinks or other activities. He's always still there for them because he says he will always remain cool and cordial with his ex's. Says they are practically one of the guys.

But I've literally seen messages where his ex's talk about missing the past, or talk about their old relationship, or get upset with him over things from the past.
