What should I do?

I'm 28 years old and I recently met two men and I am interested in them both. One guy is very sweet, smart and has a lot in common with me. He has been a complete gentleman to me to date. He also offered to help me with a situation that I will be facing soon.His problem is that he goes days without contacting me, yet he seems interested in me as well. It's a casual thing, so I'm not expecting that much at this point.

The other guy is also very sweet, and he is pursuing me much more aggressively by contacting me more. He has also been a gentleman in most ways, yet he did not walk me to my car the other night (he lives on a dark street and his city tends to be unsafe at times). I also have some questions about how upfront he has been with telling me about his job and other things. I thought I had my decision made, but now he has sent me roses to try to cheer me up about my problem (a health issue).

I don't want to hurt either one of them, as they are both good people, but I feel awful about leading one on. I haven't had sex with either one of them, so that is not an issue. I just need some advice about which one I should pick. Thanks.
