I feel so lost. My husband walked out on me and our 4 and a half month old dd 3 weeks ago. It is so out of character that every single person who knows him - family and friends - assumed he'd had some sort of breakdown. We've been together 10 years and married for 3. I thought he was one of the most honest, decent, sweet men I'd ever met. We have so much in common and until recently have been perfectly happy. He told me in no time at all that he didn't love me and was gone. He has now moved in with a woman he works with and told me they have been seeing each other since our dd was 3 weeks old. This is something I would never have suspected in a million years and has left me completely broken. He says he stopped loving me when she confessed her feelings for him - I was 7 months pregnant at the time. Initially I thought the stress of having a child and moving house (and living with my parents) must have caused something in him to snap but having spoken to him a few times I've changed my mind. His family and friends have all tried to convince him that he is making a massive mistake but none of it has any impact on him. I have tried too and suggested counselling but he's not interested. He looks like a ghost, doesn't cry or show any remorse for turning everyone's world's upside down or abandoning his child. I am trying to be strong for dd's sake but it's so hard. If I'm honest with myself I still want him to turn around and say he went mad and he wants to come home. Any advice or commiserations appreciated.
