Did I overreact? Regarding newish man

[Glowsnow]

We have been dating for almost a year although things have progressed and we are more like a couple, we just haven't put a label on it just yet. Anyway, we discussed seeing eachother this weekend and I message him in the middle of the week to ask him if we're on for the weekend and he didn't reply. I messaged him the next day and expressed subtlety that he could have given me some sort of response and that I have now made other plans for the weekend now anyhow.

He then responded that he felt put out as he wanted to see me this weekend.
But why would he not reply to my message?
He has done it before even though his plan is to see me. But then why not reply so I know what is goin on?
it really annoys me.
Aibu for making other plans?

This annoys me too. Can feel like being left on the back burner in case a better offer comes up.
You did the right thing to make your own plans. If he wants to see you he needs to let you know.

You may get to a point where you always see each other on a Saturday night, for example, in which case it's about letting each other know if that's not going to happen for any reason. Same rules apply - be respectful and keep your partner informed!

Thank you. Any acknowledgement would have been fine. I just found it a bit disrespectful that he didn't acknowledge it in any way.
