Dear Lovehacker, my wife and partner of 15 years has left me for a guy she met online in the MSN days. But she wants me to stay living in the house to fulfill her needs. She has been talking to him on and off for the entirety of our relationship and has secretly flown out to see him when I've been away.

I want to stay for my kids and give them the closest thing to a normal life as possible. And I still love her, but I guess she doesn't feel the same. Should I leave?
