I want to be sure I am doing the right thing

I am in love....there is no doubt.

he tells me he loves me all the time and it is great, he goes away a lot but he calls me everyday and although we dont live together he has given me the key to his house.

he is very wealthy though, but always takes my money when i offer to pay half, he has never bought me anything and that saddens me, his past relationships have failed all because of the same reason, when he moves in with them, he contributes very little, if he goes away he contributes nothing.

so obviouly his woman does not feel that they are truly in a bonded relationship.

such a shame, a wonderful personality, easy man to get along with - i dont want to give him up

any thoughts?
