<human>: Give me the gist of the text in a nutshell

Me and this girl were ok friends in high school but we never really hung out. Still we talk here and there since graduation last year and she said she wanted to hang out. I finally had some time and extra money and asked if she wanted to go to this fancy-ish restaurant and she said sure. What i didn't know is that she has a boyfriend she just casually mentioned to me shortly after. She was like "oh yea it's fine with him" but now I honestly don't even want to go. On top of that I have a feeling she will want me to pay for her.

It's tonight and don't know what to do. I would much rather call it off but at the same time I feel like it's too late.
<bot>: Going out for dinner tonight with a high school friend, found out she has a boyfriend, don't want to go anymore
