Does she have feelings for me or am I tripping?

Hello Everyone sorry for the long post,

Im really looking forward to getting your thoughts and questions on my situation. Ive been friends with this female for about a year now. In the being it was like a regular friendship. Over that past few months she seems to be acting weird towards me. She avoids me when there are a lot of people around, but will talk to me when there are fewer people. I wouldnt think anything of this but she is the female in our work environment who acts this way towards me. Im pretty friendly with everyone so its not like I treat her any different. She has also confided in my about her anxiety and work place issues, all things I feel like she should talk to her husband about (I probably should have meantioned shes married earlier). Shell randomly messages me about something that could easily be look up on her own, then when I respond I get nothing back. The whole situation confuses me because Im not the most sociable guy so its not like Im giving her the impression that Im into her. Which I could be because I think shes FINE AF and something about her personality is even more attractive to me, but I never expressed this around her (Probably should have meantioned this earlier as well, Im also married). Im not try to be this her just trying to figure out if Im look to deep into our interactions.
