My partner has recently walked out to be with the women he’s been having an affair with. We have 4 children aged between 1-14 years we were together over 20 years. He seems to think it’s suitable that he comes back here Friday till Monday morning to have the children. As he has nowhere to take them. He’s staying between the other women/new girlfriend and family’s house. I’m really unsure what I should do? I don’t feel it’s right he’s walked out on us but then excepts to be here weekends like having the best of both worlds. But then I feel guilty for my children. But unsure if I’m thinking like that because of the hurt he’s caused? Can any give me any advice please? How what would be a suitable arrangement? Thanks
