Love/hate

Im 29 weeks and am loving my pregnancy but am also am so depressed at the same time! Sadly i am more depressed when my husband is around. I dont know why but it seems like he just wants to hang out in his mancave when he is home and ignore me or not want to be around me. Whenever i do something he doesnt like he snaps on me! And i just dont know what to do. I try talking to him but he always flips it on me! I just dont want to feel alone anymore!!
