need to vent

My husband and I have been fighting a lot.. We've only been married for 3 months. I'm 19 he's 23. We have a beautiful baby boy on the way. I'm 32 weeks pregnant. All he wants to do is go out with his friends and drink.. That's all he cares about. We never get alone time together and I think that's important to have quality time with one another in marriage. Every time I plan for us to have a day together he makes plans to hang with his friends. Right now we are sharing a car because his is messed up. I've been waking up at 5am every morning to take him to work and pick him up. Tonight we were laying down and he had been on his phone a while and btw I'm super sick running fever and he says "I'm going to my friends for a few hours" and his friend is a major pot head.. I asked him if he could take me to my parents house which is 5 mins away cause I don't feel good and don't wanna sit at home alone and he said he couldn't that his friend was waiting on him so he got in my car and left.. He always puts his friends before me. I'm so hurt and scared of losing him but I don't think this is going to end
