Men, what does it mean when you let the woman you are dating meet your mother?

Backstory: He and I met last summer and we dated for three months. But we were not getting along and things ended between us in December. But we reconnected last month in April and went out on a couple of dates already. And this was the third date after we reconnected.

This is how things went (I'm explaining the situation because I'm trying to figure out if I only met her because he lives with her. Or because he actually wanted me to meet her)

So he said do you just want to come over and we leave together? (Because he and I planned to go to the movies together) I said ok then I told him I was coming over at 10:30 am and he said his mom would be home a little after 11:00am. And if that's uncomfortable for me that I could come after 11:30 (when it would be time to leave his house to go to the movies). I said no it's fine that I was coming over at 10:30am. When I got there he showed me around and then we sat down and talked. His mom came home and he told me to come say hi to her. And that's when we met and she said it's nice to finally meet me. And then afterwards he sent me a text saying that his mother liked me with a smiley emoji.
