Please help, Does anyone else feel like me? What can I do to help my situation?

I dont have many interests of my own but the ones I do have My husband is not at all interested in, I try getting into anything he is into and support him even if I dont perticually like its, it seems since he stopped playing MMORPG games and stopped drinking, I seem to be what he has diverted his attention to. Dont get me wrong, I am proud of him giving up the drink and love that he wants to spend time with me still after 11 years only thing that I have that he shows some interest in is the children, even then all he really does is shout at them, doesnt give any of them quality time, just wants them to go play quietly so he can try get more attention from me. When I have mentioned about spending more time with the kids, he will take them to the park and sit and watch them but does not join in their games or he will try making something with our boy but ends up doin it all himself and not let our boy do anything just incase he does it wrong. He tries hard to get them off to bed early so he gets more time with me. I would really love this but always feel that he just wants sex, gets grumpy with me when i tell him I just want a cuddle or play a game. He says he feels rejected but most of the time when he comes on to me I kiss him back passionatly to let him know im interested and we have sex (about 3 - 4 times a week) but on the few occasions I say no, he says he feels rejected and unloved. It does not matter how much I tell him I love him or show him in other ways, he does not seem to get it with out me putting out for him. I just feel he wants to know my outer self but not interested in my inner person. This gets me down alot and makes me feel so un special. I feel like I am failing at a wife because of this and failing as a mother as my children always seem sad, bored, crying or back chatting me. My husband knows I dont feel like a great mother so try's disaplining the kids more when they dont answer me or if they back chat me. This only makes me feel worse. I have so much going on and some many people wanting my attention, I can not even remember what my interests are anymore. I have tried to encourage him to go out with mates but he takes that as I want to get rid of him when I don't, just want some space to breath. Wish I could make my husband understand, I love him and my children with all my heart, just want to smile and feel good for a change.
