Should I tell my coworker I'm attracted to her?

There's a girl at my job who works in a different department than me. I'm attracted to her and I believe she likes me too. When she occasionally comes to my department she greets the three of us with a hug, but a hugs me with a little extra. I often catch her looking at me at times but she plays it off. When she leaves she always touches my arm/shoulder on her way out.

My only problem is that I'm in a challenging marriage of 20+ years.

Should I tell her how I feel to get it off my chest or keep my feelings to myself?

I don't want to make things awkward between us.
