Am I supposed to end this friendship?

[Ohokimsneezing]

So my main friendship group consisted of a group of friends and one of the friend's now ex-DP. We all used to hang out and have a jolly good time. Going out for food (trying new cuisines), going round each other's places for home cooked food and playing cards. Friend's then-DP became an integral part of our friendship group.

Friend's ex-DP has moved across the pond to study and is planning to remain there for work. Friend and friend's ex-DP were long distance for a bit, but then it ended up not working out and they had a fight over the phone and broke up. They haven't blocked each other on socials (yet) but they no longer text or call each other.

Am I no longer allowed to keep the friendship because I only met friend's ex-DP through my friend?

You don't have to give up friends. Has your friend asked you to stop speaking to her ex?

No they haven't. But they've said ex was quite rude with the breakup call

Do you want to keep the friendship?

Oh come on. Surely you can decide for yourself who you are friends with.

Why do you want to stay friends with this person?

You choose who you want to be friends with.

Thanks for the replies. I genuinely still consider this person a good friend.

But obviously there was drama. And, I was under the mistaken belief that you're not supposed to remain friends with a friend's ex if you didn't know the ex before.
