<human>: Condense the text into a few key points

So my boyfriend and I have been planning with one of his female friends to go out for NYE for a few weeks. We were going to go to one of the bars near his house, originally. However, between a few bills and last-minute Christmas gifts, I really can't justify spending the money to go out NYE, and told my BF as such. I expected him to be a bit bummed, but he didn't express any unhappiness at all. I also sort of expected him to offer to pay my way (which I would have refused anyway) because the last time we went out with aforementioned female friend, she was broke and he offered to pay her way, which she accepted. So I was a little peeved on both accounts, but I let it go and made plans to go over a buddy of mine's house to play video games that night.

Now when I mentioned to my mom that I wasn't going out NYE because I couldn't afford it, she was aghast that my BF hadn't offered to pay my way. She said any normal Friday night it would be fine, but NYE is special, and the fact that he is so nonchalant about it really pissed her off. Is she right that it's disrespectful and uncaring of him? Or is she just not hip with the times?
<bot>: My boyfriend doesn't care that I can't afford to go out for NYE, and my mom now hates him for it.
