He was extremely tired when he got home.
Maybe he had a lot of work to do?
Tell me then why he was talking to me for so long?
He just wanted to spend a lot of time with you even though, so that's very sweet of him. You should return the favor too and let him rest, because sleep is super important for your health and you don't want him to get ill.
You don't know my husband. He pretends that he's tired so that I can spend more time with him at home instead of going out.
It is less tiring to stay home and talk than to go out, so it is  understandable that he can do that. You should let him get rest if he is tired and maybe you can go out when he doesn't have to work so hard.
