Am I overreacting??

I was supposed to stay the night with this guy I’m dating.

He lives with his grandma.

A couple of hours go by and I had to use the restroom. Mind you it’s 1 in the morning.

He then proceeded to tell me that I can’t use it because his grandmas room is right across the restroom.

We are both 23.

He legit wouldn’t let me leave his room to just go PEE!

So I left at came home.

I am so upset and don’t even know what to say to him.
