i need help handling a situation.

ok. so my girlfriend and i have been together for 14 months.

we used to have sex quite frequently, but havent had the chance for a while.

new years eve is coming, and i obviously want to spend time with her... preferably alone ;)

but now she's telling me that we might not be able to because she told a friend they would chill because she thought i would be working.

to be fair, i will be working new years eve. but only until about 9:30 and was planning on picking her up right after work.

i have cancelled plans with people multiple times to be with her. why doesn't she think she should do the same?

i've tried telling her. i get a "you can't get mad at me for this, not my fault" response.
