<human>: Today is my mom's birthday. Her and I have a good relationship I would say. She is 56 years old and separated from my dad 2 years ago. She is doing well on her own so far.

Anyway, I texted her (she's at work) about her birthday today. I asked if she had plans this evening. She said she had dinner offers from a couple of friends, but she is "holding out for a better offer" (she means from me). This kind of creeps me out, but she's always been kind of helicopter-y. I let her know that I'm down for whatever, but that my brother is slammed with work until later this week. I told her if she wants to go ahead and get dinner with friends, then I will still see her when we get together as a family. She replied:

"This is the part where you say you love spending time with me and never want to pass up an opportunity to spend time with me and can't wait to see me. "

Then a minute later before I replied:

"That's fine."

I replied: "What's fine?"

She said "I'll see you next week."

Anyway, she's being passive aggressive and I feel comfortable with this assessment based on my knowledge of how she is. But now I don't know what to do. I'm hurt and pissed off that she'd act that way, but I also don't want to bring it up in fear of ruining her birthday. 

This is stressing me out a bit, and I'd love some input from people who deal with n-parents or parents with guilt-trippy tendencies.

Can you provide a brief overview of the text?
<bot>: Mom is guilt tripping me for not demanding to see her on her birthday. Looking for advise on how to stand my ground while not creating drama.
