It's hard, and I'm struggling.

I have my codependency book, I read it and take it to heart, I do my best to put what I learn into the situations in my life. But today, I'm very discouraged. I think it's making things worse.... part of me doesn't even care, part of me just wants this all to be done and over with. I'm tired of being pushed away, the steel-enforced concrete walls, and the condescending attitudes. I feel like he's looking for opportunities to make things even more difficult for me. I have the week off work for Thanksgiving, and on Sunday night I asked if he would turn off his 5:45 alarm (he rarely ever gets up at that time and has 2 more alarms set) so that I didn't have to wake up that early (I'm so trained by my alarm and routine that I can't go back to sleep once the alarm goes off) and his exact words were "OK". 5:45am on Monday morning the alarm goes off. And hour later when he finally got out of bed I told him that I felt like him indicating one action and then doing the complete opposite was, well, rude. He claimed he never said he would and that he wakes up the way he does cause he likes to (this was done in a very "informative" and condescending tone). Am I going crazy? This ongoing cycle of "Distort, Deny, Deflect" is really wearing me down. Nothing happens unless he says so, it happened the way he says it did, and it's always somehow my fault. The dog didn't bite my daughter because he was diagnosed with anxiety problems and had been showing signs of aggression for 2 years. It was all circumstantial and environmental. Since DH goes to work all day everyday, the circumstances and environment was on my shoulders entirely. DH is so deep rooted in denial that when he took the dog to the shelter, he didn't even tell them the dog had bit a child because he didn't want his animal to be euthanized! It doesn't bother him one bit that someone with a child could adopt that dog. He doesn't see that by denying the behavioral problems, he's possibly put someone else's child in danger of being attacked! Why?.... cause it must be, some how my fault the dog was aggressive. If I'm not in the situation, the dog will be fine. I'm so exhausted with this. If this man truly believes I'm as horrible as he says I am, why the hell can't we just be done with this relationship? And if he doesn't think all the horrible things he says I am..... is it really such a stretch to actually be nice to your wife? Maybe treat her as if you really did love her? Is that such a crazy thought? I don't think it is. Ok, I'm done venting. Stepping off my soap box now...
