Wow, with kids to look after you still manage to get onto AB @ 2am, get some sleep, it might all feel alright again if your rested!!
As everyone has said you need to talk to him, tell him how you feel, ask him how he feels too, like i've said to many people on here, men and women are programmed totally differently, what upsets us often goes unnoticed in the male brain, it's not until we express ourselves men generally understand whats wrong, no fault of their own, just the way we have all evolved.
Unless you tell him how you feel, it will just get worse, your feelings of resentment may grow and you may start feeling very low. Share your problems..... I doubt you wouldn't have married someone you couldn't talk to or would be prepared to help you out.
