<human>: My ex and I were together for a little over three years. The breakup was mutual at the time but still very difficult for me at least, I've done well maintaining a no-contact situation so I really don't know what's going on with her. 

Her two closest friends [25/26F] were also good friends to me during the relationship and we all really have nothing against each other at all. 

The thing is, they're clearly closer to my ex than they are with me, but from time to time will reach out to meet up for dinner or a drink to catch up, without the ex around. 

I'm feeling kind of reluctant to maintain this sort of relationship with them as any time I'm around them or see them on facebook, all I can think about is my ex, and I'm worried I may hear some details about my ex that I really don't want to hear about when I'm around them.

My question is, should I bother to maintain this friendship with them, or is it foolish of my to exclude other people from my life by association?

Can you condense the text into three sentences or less?
<bot>: My ex's 2 close friends want to meet up for dinner/drinks to catch up, I have mixed feelings about it. Shoud I bother?
