DP and I have been together for 7yrs, have two children together plus kids from other relationships. He was fun when we got together, but the fun has gone. He's always tired, in bed at the same time as the kids most nights. We spend no quality time together, and usually sleep in separate beds. Sex and even everyday affection have totally disappeared. He looks after the kids, but does very little round the house - bins and dishes/laundry when necessary. Never sees anything else as needing done - eg will load dishwasher but not clean counter/sweep floor etc. We both work full time but I end up doing most of the housework. I'm so fed up of nagging him to help out, he doesn't seem to care, and I'm now in a position where I don't even really fancy him anymore, he's just like an extra teenager in the house. Is there any way of salvaging this?
