Yall I made a big mistake...

I wish I never stayed friends with my ex. It sill makes me upset randomly.

I’m in a friend group with him and my other 2 girlfriends and he wants to start having me and his new girlfriend with my other 2 friends hang out and I’m like HELL NO.

I don’t want to be around him and his new girlfriend that’s just fucking depressing and will make me mad but I’m sure that my other 2 friends will think I’m being silly that I have a problem with it since we have been broken up for a year.

It sucks that my only 2 friends in college are also friends with my ex. We were a friend group all of college and now it’s our last semester. It worked out fine when I dated him but not when he has a new gf Bc I don’t want to hang out with her, I already had to meet her and hang out with her once and it just made me so sad.

Would u guys ever deal with this or just drop the ex as friend?
