Tough situation you find yourself in right now with waiting out D and feeling like you are ready to have sex with someone else. One year seem like an abnormally long process.
I understand the desire and feelings you have, but I agree with what PM said above ^. My vow was to my wife not to God or a piece of paper just as you have mentioned, but I still would not pursue any sort of relationship while still married in the eyes of the law.
My XW never moved in with OM, so my opinion may have been different if I was in your situation. I guess my only advice is to make sure you fully understand the consequences of your actions if you decide to pursue another woman.
I was so committed to my W that when we were separated I could not even cheat on her while dreaming. I specifically remember a couple different times where I was dreaming and had the opportunity to have "sex" with someone else and I politely turned them down because I was married.
I would say that if you feel like this is something you want to pursue why not take it super slow and just get friendly of flirt lightly with some women and see what that does for your self esteem. I know my has been smashed because of the OM and I often wonder how desirable I am to women. Even now when I can't a cute smile from a random girl it feels great.
