My friends made a group chat and are having a dinner tonight without me

In our group chat there are 8 people and i think three of us are being left out in the new one.

Recently I was being kicked and put in the big chat continuously because they didnt like the jokes, which didn't happen before.

This afternoon I was playing hanging out with two of the guys in the new chat and one who was left out like me and they accidentally talked about the evening plan.

One of them is hosting and probably didn't want us to come over his place, but the other one is a close friend of mine and when I found out the plan was trying to convince the host to invite me.

The host said he doesn't have enough food, which obviously isn't the main problem.

I really don't want to lose them as friends but I was really hurt after finding this out.

what do I do?
