What the F happened??!!?

OK, so me and my husband have been married a month short of a year and our communication has severly taken a turn for the worst. I baby this man, I have a beer ready for him when he gets off, etc. Over the past few months I have not been able to get through to him at all. He takes anything I say personally and gets all defensive. When that happens I am forced to push away what's bothering me at the time and "pretend" everything is okay. He is always either working or sleeping so we hardly ever get any time together, but is this really what marriage is? What the F happened??
