I need comments please

Hi im a 27 male, me and my woman always love to travel, we went to japan for week. I recently remember my high school friend who is a white girl she sold everything and moved to japan for about 3 years now, shes very fluent in Japanese. So idecided to message her and ask to meet up, then she brought her friends, and i brought my wife, we hang around giggling, it felted so natural just socializing with her and her friends. shes really pretty, and ive always thought about sleeping with her even back then, its always running thru my mind constantly while we were together. Anyways we hung around lunch she had to leave for work, so she decided to invite us kareoke after her shift, me and my wife went back to the hotel decided to rest coz it was a long day. My wife is really sickly and she decided that she would stay at the hotel and let me go out by my self. So i did, we met again at the kareoke, hanging out with her friends, she has a bf but did not invite him, i felt good connection having conversation with her and also being touchy with her, i touch her legs whisper in her ears and everything felt natural with no awkwardness. She invited me to crash at her place, and ask if thats ok with my wife, i am yah no problem, and i ask her if thats ok with her bf, she said no problem, i have a feeling that she did not tell her bf at all, anyways i had to crash somewhere coz the train stops in the morning and i had to take the first train early am to go back to my hotel, we called a cab got in to the cab, i looked at her man, i just want to jump in there, she look so hot with the view im lookin at, the only problem is im too drunk because she gave me this Japanese drink name strong and it is pretty ******* strong, anyways we stop got out of the cab and walk to her place, got in to her place. Got comfy took off my shoes, she played some music, offered me beer and food, i didnt drink, but she did, she was feelin it, were too comfortable for each other. I could not find a sign if she wants me or not, i feel like if i made a move it wouldve happen, but she was too far from me and i was too drunk to recognize anything i pass out on her bed for an hour and i had leave again for the train first thing in the morning. She slept at the floor, But at the kareoke bar i was so into to her touching her legs and she wouldnt have a problem with it. She took good care of me when i was at her place coz i was her friend. Do you think she was just friendly, were both taken, and do you think we couldve have sex that night? Ididnt want to cheat but its very tempting and i also didnt want to embarrassed my self if i made a move and shes not feeling the same way. Im bad with signs and dating but i really wanted to **** her. Ifelt like it was good nothing happen but then you only get that chances once in a lifetime. Someone tell me your oppinion
