Intrested in me or my money?

I have been widowed for 3 years. I am more than comfortably off. I met a man 3 months ago. As the relationship is progressing I now find that I am putting my hand in my pocket for everything. He rarely buys a meal or drinks when we go out or puts his hand in his pocket for a take out. He does drive 1 hour to see me but has now mentioned that he is finding it too expensive and can I help out with petrol money. He has obviously sussed that I do have money. I am beginning to resent it. Should I tackle the problem head on or just call it quits.
