My boyfriend lies about small things all the time?

I need some advice on how to get him to stop lying about small things. For instance, he told me that he was at a friends house to wait out the hurricane and then I asked him what the building was made of, wood or concrete and he said concrete when in reality he was in his wooden apartment because he didn't want to stay at my house with my family there(eventually he did when I got upset after I found out he was at his unsafe apartment) and today he told me he was visiting a friend because he was jealous that there was someone at my house when I'm reality he was sitting on his deck ignoring my calls. He does this with everyone, he will text his friends when he's with me and tell them that he's working or cleaning so he doesn't have to talk to them or tell his brother that he is sleeping when he's getting food with me so his brother doesn't ask him for food. Then we he doesn't want to come to family dinner at my house he will try to tell me to lie to my family and say that he's sick or at his sisters even though I was just with him. I'm worried his "small" lies will get larger and larger.

EDIT:

Well when we first got together he told me he was 24 but he was actually 28 and he lied to me about having kids too. And he lied about being married(separated for 2 years) he came clean about it all after a couple of weeks and ever since then he hasn't lied about anything big, except about 6 months into our relationship he does me he has another full sister that he lived with and two half brothers that he's never met, he said he didn't tell me because he wasn't proud of his sister and because he doesn't even know the two half brothers. He also lied about how he got to this country. He always tells me the truth eventually but it's just so annoying and makes me feel like a fool.
