Chery they recommend me to you.

hi, i don't think that its love but i have liked tihs guy for the past four years. We have never talked but we do know each other b/c our sisters used to be friends. I think that he liked me too. Last January 2004 I found out that he got marry and it did hurt, but then i decided to stop thinking of him. So i tried, but when ever i used to see him by my house (b/c his mom leaves by me and he would go and visit her) He would put his face all serious and since i knew his wife, she talked to one of my cousins. He would always get all serious and he wouldn't look at me, just to say hi or sometihng. Yeah so i tried to forget him but it was kind of hard at same tme. This year on January 2005 i found out by my cousin that he got divorced. I saw him this year on August and i, well my feelings for him came back. He was flirting me and my cousin says that he wants to talk to me, but he is afraid that i'm going to turn him down b/c he was married before.
Now, my question is, would it be wrong if i would go out with him? Since i have never had a b/f and i'm kind of shy. Can anyone please give me advice?
I wish that i could talk this to my mom, but i know that she wouldn't approve with that.
