We have been married for 17 years and have 3 children ages 17, 16 and 15. I thought we has a wonderful marriage until 10/18/13 when she told me she was unhappy and wants me to move out so we can be separated for awhile. She has no where to go, I have friends I can stay with. I was completely blindsided by this. She has infidelities in the past. We have started seeing a marriage counselor.
