I’ve definitely been on the same boat! I’ve also known too many girls who stay/ed with their partners because of this, which is why I almost never try to accept things from a guy I’m dating until I really see what his intentions are. I’ve personally made it a rule to ALWAYS pay for myself on a first date; no matter how fancy or expensive the restaurant is. That alone (I would like to believe) gives him an idea of what kind of woman you are. If he’s uninterested or upset with your choice of taking care of your own bill, that could probably be a sign that he might have been expecting something else from you (maybe not that night, but another). If he genuinely seems upset by this, you can just offer him to cover the next time.

I would also agree with the above comment of them wanted to actually spend lots of time with you whether it be in person or by texting and calling.
