Feeling unappreciated.

I'm feeling really unappreciated by my SO and it sucks. I'm 26 years old, 22 weeks pregnant, I work full time, I'm going to school, and I have a 5 year old. I take care of the house by myself for the most part. He'll do little things like take out the trash or a load of laundry here or there but that's it. Then if I don't feel like doing anything when HE wants to, to him- I'm being a bum or I'm "at home too much". Yes, when all my obligations are handled and I'm off- I DO want to be home.
 
Is it too much to ask to just be appreciated? A foot rub? A romantic night? A thank you? He works and I'm thankful for that. But right after work, he goes out to his horse stalls and stays out there for a couple hours. And by that time, I'm already tired and don't wanna do anything. 
I'm just another complaining pregnant woman.... that's feeling unappreciated.
