Did I make the right Decision?

So, I have wanted to date my friend Megan for years. She knew I liked her from the get go, but told me she just thinks of me as a friend, and "i'm not her type". Whatever the hell that means. When we first met, I was a coach surffer, and going from job to job. It's funny how that saying goes, everyone is your friend untill you need them. BUT!!! I was able to get my life together, and I am doing pretty well for myself now, however, that whole time I tried to go out with Megan, but than she got married, so I gave up, and finally accepted we will just be friends. However, she got divorced, and over the past few mouths we became closer friends, and Last weekend she layed a bomb shell on me, telling me how much she loves me, and she is sorry for not giving me a chance before. And now she wants to be my girlfriend.

How does that saying go, The shoe is on the other foot?

I told her I just wanted to be friends for now, becasue in my mind, I only think she wants to date me becasue she can't find anyone better. You know having a girlfriends support would have been great when i was homeless and poor, but now that I have a good job and my own place, now she wants to date. I am affriad if things go bad, and I have to rebuild again, she will just bail on me. I did sleep with her of course..... But I also banged her when she was married. ~~HI OH!!!~~
