Three years ago I discovered my husband was having an affair. There was an incredibly painful period where he begged me to take him back said I was his soulmate. Usual claptrap. When I discovered that he had had two Christmas dinners, one with our family saying he would be nothing without us. Then two hours later with the ow and her parents discussing how resilient the children would be to divorce. That was it for me. I finally divorced him. He couldn't believe it. Said I had broken 'for better or worse' marriage vows. My issue now is our four children. He has seen them three times over the last year and always when it suits him. They are with him now. He was supposed to have them for two days. An unexpected 'course' for work came up over the bank holiday weekend. That means he's done one day in the summer holidays. I've been invited away in October. I asked if he will have them. He had replied he will 'see if it fits in.' I never say a word against him to the kids. They went off today happily with no thought of how little he does. He is their dad. Am I unreasonable to be so filled with resentment. I can't have a life while he picks the moments of parenting he fancies. I am so worn down by it. He will not commit to regular contact,
