Again you are making assumptions and placing demands. The assumption that you should not pay for anything and demanding everyone else (the couple) does. Sorry to break it to you, but that's not how it works. As I mentioned before. You and they failed to set the ground rules as to who is paying what.
We have meet guys at a hotel before. And they payed. We were to meet guys at hotels (never went through due to illness) and we were going to pay. There is NO dynamic demanding the couples husband or boyfriend pays every time. That's being in the lifestyle with a conceited mind set .
DISCUSSING and AGREEING to who does, pays is what stops any misunderstandings and stops countless threads like this one being made where you are looking for the validation from others for your actions.
Sorry, but you both brought this situation on yourselves.
