Marriage Issues & I dont know what to do!

Jessica
I am 35 weeks pregnant and will be married for a year in Sept. We got engaged Feb. 14, 2015. Well I know lots of people say your pregnant you just have hormones but I really feel its more than that. My husband and I have been having issues about the children because he feels a lot of my techniques are flawed or shouldn't be obeyed by the children which sometimes lead my step children into being disrespectful towards me for ex. bedtime is 8:30 and he feels thats too soon... I tell them to pick up after theirselves and he feels they are too young (4 & 6)... Finishing their food when he lets them eat chips, cakes and drink kool aid all day... Staying up watching tv until 11 to 12 at night on school nights... Well basically all my parenting skills are wrong to him. Any way I have left him and went back to my moms house on several occasions because sometimes things really get out of hand. Well on top of that my husbabd does not spend time with me even when i practically beg for it. He spends time with his male cousins that come pick him up from the house and/or sits in the yard in the car and smoke. When he come in the house finally and im finally done with all the house work for the night he just climbs in the bed and goes to sleep. After trying to wake him so we can spend some time together he just gets upset and says very mean things. I dont know what to do. Ive told him how i felt and nothing changes although he says they will and Im becoming unhappy because I have nobody. My family doesnt live nearby and i feel so alone and neglected... Is this what marriage is about? Just dealing with things and sweeping them under the rug? Marriage Couseling isnt a option we couldnt afford it and i really doubt he would go... i kno its long but please help me
