got a party with an ex 😐

so my friend group which is all girls became really interlinked with another friend group which is all boys. a couple of the girls began dating some of the boys, so did i, but recently i broke up with him. all the other couples are still together and our friend groups are still interlinked. i have a party coming up soon with the whole group and he’s gonna be there 😞 i don’t know how i feel about going because its really awkward! we broke up on alright terms and it wasnt even a long relationship. all my friends are begging me to go but i don’t think i want to! im highkey crashing out 😐😐
