Kathy I agree, My first marriage i stuck it out for 2 years trying to get my wife to give up her lesbian lover. Now i have a wife with PTSD. She thinks she will be happier away from me and with her old boyfriend she new 20 years ago. She says im a good husband and father and doesnt know why she want to leave and she feels guilty. I dont think it is all PTSD. Mid life crisis maybe. I havent seen to many people leave spouses for other interests in this forum. Usually because of the wear and tear of the depression, anxiety, stress, anger. I can see that if it is abusive or a bad for the kids, but because of a fantasy from a loving relationship 20 years ago. I dont think so. I dont leave marriages because im unhappy. It can be worked through. Unless of course your spouse is more caught up in another person. Both spouses giving it 100%. If not its shot to hell.
