<human>: Can you succinctly summarize the text in 1-3 sentences?

A very good friend of mine is having a low-key small NYE party at her place to which we were invited about two weeks ago. I asked him if he wanted to go and he not once in these past two weeks declined the invitation even after I asked him REPEATEDLY just in case he wanted to do something else, up to yesterday at about noon. No response one way or the other. 

Only now, about two hours ago, did he send me a text telling me that so-and-so is having a party and he wants to go to that one. We hardly ever spend time with my friends due to me being acquiescent and spend time with his. I'm not ok with cancelling my plans just at the last minute without a good reason.

<bot>: NYE plans set two weeks ago. Boyfriend wants to change them today, even after much questioning if this is what he wanted to do. I'm not ok with cancelling at the last minute without a good reason.
