Is AUTHOR wrong in the post ? POST : My GF and I have been dating for almost a year. As of late, I really noticed that she costs a lot. I mean she goes to Starbucks every single day, eats out atleast one meal a day, etc.
Lately I’ve been blessed and have made ~$5000 this month. This information, I chose to share with GF. 
Since some time has passed, my GF has been wanting to go out and eat and do things, without realizing that I myself have things to pay for. So this lead to her wanting to go to a restaurant last night and I said I wanted to save some money before going out again.
I’ve spent $200 in the past 3 days and she has spent $30.

Whenever I say no to her she’ll say something like “u don’t hesitate to spend money and go get food with ur friends but when it comes to me you say no”... I’ve gone from feeling 100% validated, to talking to her and feeling 100% in the wrong. AITA here?
