been there...At one point in my life suddenly felt happy to see man other then my husband,felt "click" with him,(mutual). It felt so good to have his attention and company,to be able to talk,his availability was addictive(something you don't have in many marriages).I knew it was wrong:I have a family,he had a family, families knew each other...That was hard,I fought hard with my feelings,I knew I had obligations as a wife and a mother,and no matter how much he implied that he needs me,he is not happy (and finally he divorced) , I could not allow myself to let him know how deep I feel for. As a matter of fact ,in spite of having 2 kids,for the first time in my life i wanted ,really wanted to have HIS child.That scared me,showed me how much I loved him. My relationship with my husband was/is rocky, ...But as I said I had obligations.So I let him go, I pretended he does not matter.It took me 7 years to get over him. Still miss him.But I am convinced that I made a right choice,otherwise I would not be able to live with guilt. So ,IF you love your wife,reconnect with her,try to understand is your friend is desirable because she is available and forbidden? if so make a right choice,your wife's love will help you to cope. Good luck.
Life is a choice,so is happiness I suppose,and we are the ones who can make a choice.
sincerely
