<human>: Can you summarize the given text in a few sentences?

My birthday is Tuesday, but we both work crazy hours so spending time with each other during the week is impossible except when sleeping. I was hoping to spend time with him this weekend in between my small jobs and just hang out. Maybe a fire, go to a lantern festival, have a nice dinner. Which I've been talking about for awhile. Well a couple days ago he tells me he's going to go visit his mom and sister than live two hours away for the weekend. Completely random. He only goes up for holidays, birthdays, etc. And when he does go he absolutely hates not bringing me. 

He was supposed to return this evening but now he's saying probably tomorrow. He texted me when he got there last night and then this afternoon to say he was staying. Two texts in 24 hours.... Not even one to say a simple Goodnight or anything. 

I'm not mad that he's spending time with his family. I'm mad he chose this weekend to go and left me all alone with absolutely nothing to do except chores and work on our business. Like I always do, but he never does. He could have waited until next weekend when we both could have gone, but no...

Am I silly for being mad? I don't know how to react when he gets home after being left completely alone and bored the entire weekend.
<bot>: Boyfriend left me on my birthday to randomly see his family for no reason. Could have waited to take me next week but didn't want to. So I'm left bored, lonely and pissed off when I should be celebrating.
