Im pissed. Should I be?

I don't get to spend many weekends with my boyfriend because of kids out of state, he has multiple businesses etc. We've been together 5 years.

This weekend we made plans to go biking or take a small hike Sunday. He had his high school reunion the night before.

I called him and he's trashed. He was dancing and drinking all night. He said no way can he go biking or even take a small hike. So I say am I even going to see you today? He says I don't know baby I have to go into the office my brother is calling me about work. Maybe we'll get dinner or something I'll let you know.

WTF. We planned this for over a month. Like he's ' not sure' if he's seeing me today?

I did see him fri eve we went on a date and yesterday I stopped by and we messed around.

Am I being gaslight? It's feels off but I can't put my finger on why I'm so freaking mad

Im pissed. Should I be?
