Moving leg towards girl cheating?

I worked with this female that i found kinda attractive. I never flirted or had sexual contact with her. We were friends. One day some co workers including me and her sat a table. I might be remembering incorrectly but i think she sat next to me and out legs touched and i was turned on from that. by the way i have a girlfriend and she has a boyfriend so. I think our legs separated and I eventually moved it closer again cuz i guess it just felt good feeling another womans leg after years with my girlfriend. I never cheated ok my girl before so I don't know if this is considered or whatever. I have bad anxiety and have had panic attacks in the past about small shit like this. Please some advice and insight would be helpful thanks
