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

Long story short is I made a mistake in a doubtful moment and looked on Tinder for about 20min, messaged one person but was not trying to hook up, I was really just browsing. This is a ramification of me doing something stupid 2 weeks ago and she threatening to end our whole relationship & fly back East.  She found out and is using the credit card I shared with her to pay for hotel and airfare to leave me totally $950 this week! Long story short below but while I deserve some punishment, this is over the top and am debating whether to cancel the card or keep supporting her through a big licensing exam she's been prep'ing for 2 months for and is over tomorrow. **She moved cross country for me so I feel like I owe her but should I break it off & dispute the credit charges or accept this as the conequence of my actions?**

Gf & I share FB password to link our AirBnB acct since we live together & rent our 1BR when we travel. We were Long Distance last year acct nd been living together now since February. She's from the East Coast and finished grad school so she's been prep'ing all year for her Professional Licensing exam (taking it today & tomorrow) so since I make acct derangement good salary, our arrangement it's I pay for acct derangement most everything (she has her own student & car loans).

I realize that I crossed a line and broke her trust, but she is trying to pressure us into engagement when I'm not comfortable with that after just 1 year (1/2 LDR) and she has clinical depression which I'm getting an understanding of but it takes time.
<bot>: gf caught me looking at online dating (I explained I was just looking) and went behind my back and against me telling her not to get a hotel or spend on my card.
