It's good to know that you're already moved on...sometimes let go is the best choice...be strong...dude...you're a man...
I'd been there too...not quite the same thing, but more and less, the same...I'd been in love with someone's wife... she was also in love with me...I'd known her for years back when she was single and didn't pay much attention for the signal she sent for me....hahaha...
And when I found out about this feeling...it was all too late...she is someone's wife now...although she didn't have a happy life with her abusive husband...
We talked together, we laughed together, share the same feeling together, and there's a lot of chemistry between us...and we made love...and I was taking care of her, and asked her to divorce and then asked her to married me...
but her husband found out about us...in the end...she had to choose between her childrens and the family reputation or me....and she choosed her family, and me? After sometimes, I finally made up my mind and said to myself...I have a life and must go on...so..move forward...
my humble opinion mate....move on...find someone else...or get it on with your wife...
life is to much beautiful to waste....
and stop pity on yourself...
