Exhausted,pregnant again,and no help

Julie
My lo is a little over 12 months and I'm 3 months pregnant with number two. She still wakes 3-6times a night crying and wanting rocked and I'm not getting much help at all from my husband. He goes to school 4 days a week and is done by 2pm. He doesn't get home until about 4, eats dinner and makes a huge mess in kitchen and then goes downstairs away from us for the rest of the night by 6pm every night. He may come up and kiss her goodnight but that's about it. He kicked us out of the master bedroom at five months and put a twin bed in the nursery without my knowledge,just expected us to move without a word. I'm now working part time, paying for all the daycare out of my paycheck and am responsible for all child care. If I ask for a nap he pitches a fit and gives major attitude and let's her cry long enough that I usually get up anyway to see what is happening. I get about 3-4hours help from my mom on Saturdays but I'm so tired by then all I want to do is sleep. The house is a literal wreck as he is a hoarder and I gave up trying to keep up with his messes and my daughter's months ago. Anyone else in the same boat? What are you doing to survive....get energy? I'm drowning here.I have 4 inch roots in my hair because he refuses to watch her most weekends so I can get my hair done, haven't had it cut or trimmed in almost 4 months and my eyebrows are ridiculous. I do good still to get a shower three times a week. Maybe just needed to vent or know I'm not alone.
