X said I can't go on a trip but we can be FWB?

So me and my x boyfriend broke up two weeks ago. We dated for a year and a half. We slept together yesterday like all day and it was great. And then today he's leaving for Palm Springs for the weekend with our mutual friends and I asked him if I could come and he kept saying that he's not gonna ask the host (our mutual friend) if I can go because that's weird since I'm his x. I'm so upset, so he can fuck me all day but then once it comes to a trip I'm forbidden to go and he won't even ask. Am I overreacting ?? And obviously I'm not going but how do I even deal with my x at this point ?! I'm sobbing in bed :(
