Please HELP!! Blended Family Issues

So I work tomorrow (Easter) and I had plans with my bf to attend the second service at church as he has work as well and it would’ve been our first holiday spent actually together. Meaning we’ve had to make up for holiday afterwards or before due to work schedule. Anyway, he informed me that he is going to earlier service cause his mom is doing something. Meanwhile I can’t even go to my family gathering cause of the time it’s at. So of course being on period I’m emotional and he doesn’t see the reason why. Like if this is the guy I’m moving in with and want to spend my life with why wouldn’t he have the decency to invite me to his earlier family gathering? Should I be concerned or am I overreacting? Mind you we’ve signed the lease and officially move in on Wednesday of this upcoming week.
