I'm so tired of my husband, need to vent

Many times like this I question if married the wrong man. We will have been married for 6 yrs come march. He ALWAYS has a problem with my family. Tonight its Christmas eve, I told him not to come by but bc I said I did want him to be there he shows up anyway. I appreciate it, sure. And yes I want him there to have all my family together (husband, 2 yr old, and immediate family) but bc I know how it was gonna turn out, I told him not to come by. I digress...there are abt 25 ppl in this house so I cnt keep eyes on my son every second but I check on him several time. Of course my husband says indidnt bc he never saw it. We r abt to leave so I'm gathering up things and apparently my brother thought it was a good idea to give my son cake at almost 10pm. Well tht sent my husband over the edge. He texts me as I'm on my way home. I dnt respond. Only to come home and hes pissed saying it's my fault bc I should've been watching him. I dont get how that's my fault. Or how everything that my family does is always my fault and he takes it out on me. EVERY SINGLE TIME. it always comes in between our marriage. Which in turn and that we end up not being intimate a lot of times bc he chooses to be pissy. Right now I'm just over it. And to add insult to injury, we are expecting another baby. I really think I'd be better off without him. Less headache, worry and stress. He wants sex every day but that unrealistic. I wrk full times and take care of our toddler most off the week. I take care of the house, laundry groceries u name it. I swear, he has it made. So my favorite holiday is ruined bc of my stupid husband.
