I’m (M22) paying for all dates with a girl (F21) I’m exclusively dating for a few months, but am kind of uncomfortable paying for the whole vacation that we are planning (we didn’t talk about it yet but will plan it soon). How can I tell her that?

Hi guys, dating this girl exclusively for 3 months now. She is a student while I’m an entrepreneur so our incomes are vastly different and I don’t mind paying for dates at all. However, we will plan our first vacation together soon and I’m kind of uncomfortable paying for everything, but I’m not sure how to bring that up, since we never talked about finances and I paid for every date till now.

What would be the correct approach to this? Because one thing is spending 20-30 dollars on a meal or something, but the other thing is spending 400-500 on someone while travelling. Help please.
