This is the reason I don't get involved with other women in the first place, lol. My girl used to freak out over things like this as well. I'm aware it's a her problem, but you give and take, and I don't feel I'm missing out on anything. So I gave in.
Because you're running up debts for her, without her consent, and then getting annoyed when she doesn't pay them back. You don't get to spend other people's money like that. Spend what you're happy to spend or, if splitting everything is important to you, have the conversation before you spend the money.
Why do you want to save this relationship? It doesn't sound like there is much trust or respect in either direction, so why not just move on?
If it was her going out with a male colleague he would feel uncomfortable too. I get some toxic vibes.
