Would you girls go on vacation with your boyfriend, paying for half the hotel and ticket if he makes 15 times your salary?

My boyfriend is 33, I am 25, we are dating a year. He invited me on vacation, but with this condition.

I was taken aback because he works in a foreign company and earns more than I do.

I would give 60% of my entire salary and he only 5%. Is it worth breaking up because of this?
