I have been married 15years. Together 19.i discovered my Hb was meeting a work colleague for coffee behind my back. When I asked him about this. He said he had no friends and she was his only friend. Hb is 39 she is 22. We have 4 young children. He left end of Oct saying he needed space. He says our marriage is over. He was meeting this girl in car parks after work at 1am in the morning. He says nothing has happened. Just he fell out of love with me. We had a good marriage. I'm heart broken. My kids are very upset and taking it out on me.
