dad not acting as you expected? vent

I really thought my BF was going to be different during pregnancy. Like he'd be nicer and more attentive to me. Pretty disappointed. He still wants to go out drinking 2-3x a week. Hasn't helped me get set up for the baby. My sleep has been crap and he complains about his sleep...I asked him to rub my leg last night as I've been getting Charlie horses almost nightly that make me jump out of bed. He said no and fell asleep soon after while listening to a podcast. We aren't intimate anymore. He talks to his family about how he's ready and excited about the baby but hardly talks to me about it and I get the feeling he's not going to be much help when the time comes. He's 36 years old btw so don't think he's going to grow up much now. I'm really feeling let down
