Is there a problem here if a man who has just met for a long time is willing to pay back 3 thousand's credit card for a woman
This man wants to prove that he cares about this woman by this behavior. It is not clear whether he really wants to or just pays lip service.
For men you just met, don't jump to conclusions yet. You'd better get to know each other by getting along with each other first, and don't be confused by each other's routines.
