Boyfriend Troubles

Hey everyone! So my boyfriend and i have been together for over a year and this week is a milestone birthday for me and he can’t make it. I won’t see him all week and he knew we wouldn’t be able to see each other until after my birthday. Yet he still hung out with all his guys friends instead of seeing me the one day he could. And now he is saying he is too busy to make it to my birthday dinner we planned. What do i do?
