lack of affection

My husband says lately I have been pushing him away. I truly don't mean to. He says I shrug away from him when he goes it to kiss me. I truly don't realize I do this if I do. I ask him to shave almost every day because his beard really irritates my skin and it's no excuse I'm just not feeling as affectionate. My sex drive is not up. It's down. I'm 6 months pregnant and extremely emotional. I feel like I have no help and if I ask for help I have to ask several times. Yesterday I spent the entire day cleaning, doing 5 loads of laundry, packing his and my suitcase to go away tomorrow. And he had told me he would help me with laundry and he didn't because I wasn't feeling good. I took an hour break and watched tv on the couch only for him to come out and ask to have the tv so he could play video games with his friend online. So I said sure got up finished another load of laundry and went into the bedroom. And then this morning we got into a fight because he says I don't give him affection. I'm just not feeling in the kissy mood and it sucks. I was just in a bad mood. I just want more help around the house. It's hard for me to get up and down a lot. I just need to vent.
