(sigh)....I love Gucci, but AFWAW dude...the 27 year old is going to get hurt in this process, unless she wants to get jerked around by you as you get jerked around by your wife. So you date 27YO for a few weeks, the wife freaks out and begs you back, so you go back, then the wife leaves again, you call 27YO, she is hurt but goes out with you again....2 weeks later the wife freaks again...rinse repeat rinse repeat...this poor 27YO has no idea what kind of drama she is about to join into.
PLEASE don't date if there is ANY chance you will take your wife back yet again...PLEASE.
This advice is not the same for everyone but in your case...please don't take that poor young thang down the road to hell you are on.
Get yer act together, and THEN date all the 27YO's you want!
