What’s going on Should I give him space or act like everything is fine?

So my B/F and I recently went away on nice weekend holiday overseas everything seemed perfect we both seemed to have had a great time until we came back. We have been together now for 9 years we don’t live together but spend every weekend together, special events together and holiday together.

when we came back from holidays he was not feeling well he had the flu so I was unable to see him for a couple weeks because he didn’t want me to get sick, which I appreciated, he then started to apparently work really crazy long hours telling me his working 14 plus hour days which meant basically I then couldn’t see him on the weekends either this went on for 5 weeks then I finally saw him and he advised me that he hasn’t been thinking straight lately and been stressed at work but is happy in our relationship.
Over the last week he has been telling me that his been flat out at work yet I know that is not true as I drove past his place and saw his home so I have come to the conclusion that if his wanting me to know his home he would tell me so and must been just wanting time to himself without saying it.

should I tell him I know that his been lying to me, should I just wait and see if this is a temporary thing or should I just give him space and see if he opens up to me?

What’s going on Should I give him space or act like everything is fine?
