My DH has behaved like a complete twat. 18 months ago he started an affair and left me and our two children to be with his (much younger)tart. This is the second marriage she has wrecked and she sounds like a bitch from hell. Anyway, I've been coping... and DH comes to see the kids twice a week. Actually, he spends most of the time texting his tart, but the poor kids are happy to see him anyway. My DS is gutted though. He's twelve, and a very sensitive and thoughtful little chap. But he's becoming withdrawn and angry. It is not possible to reason with DH. He has only ever cared about the children in a "PR opportunity" sort of way, and has never tried to give them any emotional support. He just tells them lies, like "Daddy works so hard". (Yes, I know he spends a lot of time on the job!!) DS knows the real situation because stupid twat DH gave him a phone complete with sick messages and pictures to and from his tart! I give him all the love and reassurance I can, and I have tried to get him interested in other things, but still, he is terribly lonely and sad. I don't know where to turn. Any ideas?
