What are some reasons why a guy doesn't pay for a girl on dates?

If they like a girl, have money, and not in debt?

I’ve been seeing someone for the past 5 weeks and he has never offered to pay for me. He pays for himself though which is refreshing because I had a broke ex. He works 54 hours a week as an Auto Technician at Lexus. My friend even told me he does very well for just age 21. I’m not a gold digger at all but I’m just wondering why he doesn’t ever offer to pay for me.

It’s not a big deal even though everyone says it’s a deal breaker for them. Just curious. I paid a beer for him at the bar once to be nice and let him know it’s okay to pay once in a while without saying it. He’s never even paid $3 for me. He seems to really like me though for calling me every night.
