How would you handle your significant other acting like a whole different person?

So my boyfriend since he started working has been acting like an asshole towards me. I have noticed a whole change in him completely he's been constantly critizing me at times then just not talking to me hardly at all for days. I have also noticed when I try to lay on him or sit next to him he'll move away. I don't know what Im doing wrong or why he's acting like that. It's weird to be in a relationship with someone going on 7 years and you go and pick them up from work and they attack you if you ask how their day was, he tells me he hates his job and not to ask him anything about it. Then when we go home just ignore me all day long. It's really affecting me and I don't know what to do.
