Ive become friends with a colleague from work, she's 12 years younger than me (48/36). Neither one of us has ever been married. Marriage was never a priority for me as I was constantly on the move for work. For her, work and caring for her elderly parents are the priority. We get along very well, have a very similar way of thinking, and share quite a number of similar interests. Having said that, we only get together every other month or so, usually when she's available for lunch.

She's a beautiful, intelligent, and outgoing woman and guys are always hitting on her. While friendly, she keeps them at a distance as it's really hard to gain her trust. However, she's made it clear that she does trust me.

I sometimes wonder if she might be expecting more than just friendship from me. That's somewhat odd as I think she's out of my league. On the one hand it would be easy to know, that no, she's not looking for more because if she did we would be meeting way more frequently. On the other hand, when we do meet is like not time has passed by, we end up have very deep and personal conversations.

Thoughts?

PS
No, neither one of us is gay (not that there's anything wrong with that).
