Im with you on that one actually! He stayed the night in the spare bedroom, brought me coffee into bed in the morning, to be honest im indifferent to these actions, as they mean nothing. I feel sorry for him, he seems lost. Happy is not how i would describe him.
Re kids-yes absolutely, i have a feeling it was a one of thing and he wouldnt be asking to stay here, i realised that it was totally selfish as today he was moving out from the apartment that he was staying at elsewhere (I dont actually know where to, didnt ask). At this stage it is much healthier for the kids, daddy works during the week and comes to see you over the weekend, until we have a conversation with them.
