I think it's just fine to accept gifts, and favors from your suitor. However, it's a big no if you're just entertaining this man just because he's rich, and not because you truly like/love him. I think it's quite unfair. As for me though, I have a suitor who has already been courting me for almost 8 months, and he's also fond of giving me gifts. I try to give back to him as well by treating him to dinner, or to the movies sometimes.
