Lostdad - sorry it has come to this. I do know exactly how you are feeling. My STBXH walked out in Feb saying he no longer felt the same, yet I have lovely cards for anniversary (last Oct) and Christmas, saying all the usual lovely words. A beautiful necklace that he gave me for Christmas. In December he said he could never ever leave his daughter, when the neighbours split up. Then in Feb he said he had been unhappy for several months, had not loved me for several months.
I persuaded him to talk to me, he came back for 6 weeks and walked out again with no warning. When I asked him how he could come back and be so loving and affectionate to me if he didnt love me, he just said that he was trying hard. When I said to him that normal people dont just walk out, they try everything to fix their marriage, he said I did........ I said no, staying for 6 weeks while texting another woman all day every day, 100 times a day, 8am til midnight, emailing her, facebooking her all behind my back was not "trying hard". He also refused to give up the contact with OW.
so like your wife, he tells everybody that he came back and tried everything, but in truth he didnt and like you when DD is old enough I will tell her the truth. Are you sure that there is nowhere you can go? Friends, or family? It will be hell for you to live there with her and it will not be good for the children in the long term as you will not be able to keep up a happy facade for long.
Im not trying to hijack your thread, just trying to explain that my story is a lot like yours in some way and that what you are feeling is totally normal. I really do think that you need to get legal and professional advice, see if you can get some counselling for yourself if you want to talk everything through. Also, you could call the Samaritans, they are there for everybody, just have a look at their website.
Life does go on, I was devastated when STBXH walked out for the second time at Easter, devastated again when he led me on with a lovely date and then wrote a nasty letter. At that point, I took control, ALL thanks to advice on here and divorced him. My Absolute is due any day now.
6 months on, I am feeling a lot stronger and happier than I have for a long time. Just take one day at a time, is all I can say. If you get very down, then go to the doctors for some help and advice. make sure you know where you stand regarding access for the children and maintenance etc and make sure you get plenty of help and advice from friends in real life. Please feel free to PM me if you want somebody to talk to.
Take Care
