Is there something wrong with me!! (A little long)

For the past few months now my husband has been very distant from me when it comes to having sex or any kind of affection to me, he doesn't kiss me himself it's always me having to kiss him goodnight or goodbye and me saying "I love you" to him he never says it first anymore, at this point I feel like our 14 yr relationship and 5 yr marriage is over, we have 2 kids. We spend Saturday the 12th just me and him while our kids were spending the night at my parents place and he just kept bitching about there's no need for "Us" time at all and he would rather have the kids home, we NEVER get a night without the kids ever. I just don't know what to do anymore I'm sick of this.

Our sexless marriage is because of him he says he's tired but he I only works half the month and he says he's ALWAYS tired but yet he can stay up til 11-12 drinking beer watching tv or going to the bar with his work buddies but if I want to go out I can't cuz it's money I'm not allowed to spend cuz I'm a stay at home mom to our 2 kids. when ever we are out at his friends house with all his other buddies from work there and their kids I go stand by him but the minute I'm standing by him and he has to moved to the other side of the group or the house and he doesn't talk to me at all while we are there.

Sorry had to vent. I just really needed to get it out there off my chest, I talk to him about it all the time and how I feel and what I think but to him I'm just dumb for thinking that way and need to just grow up.
