to you serious women out there....did I make it to the "Friend Bucket"?

I'm separated, and things aren't totally cleared up with my personal life yet, but I'm making the change to be a happier person. I'm not actively dating until I have closure on things, but I met someone purely on professional grounds, and well it's developed into a friendship and I'm beginning to like this person a lot more. She has invited me over multiple times for dinner, we've conversed about our jobs, our personal lives, she's been inquisitive about my relationship and status of it, she's asked whether I'd go back to my wife, etc. She's taken me to sports games and we've shared dinner out. I am really starting to admire and feeling a physical attraction to her and want to go to the next level, I haven't forced the issue just because I don't have closure on my current situation. She has told me that she really enjoys hanging out with me and has a lot of fun with me. However, I feel like I am somewhere between being a "friend" and being someone that she likes too. But I can not tell. When we part ways, we usually give a hug and kiss on the cheek, but she doesn't really motion for anything more than that. She is in her mid 30's and tells me she is looking for a more serious relationship to start a family with. We have both acknowledged that we both have a lot in common together and her best friend told her; "it's like you two have been friends for a long time." Is she just not sure of me, or are we just "friends" from now on?
