What does it mean that a guy invite staying his house when a girl visit his town for a week?

We aren’t in a relationship.
We have been a kinda friend now, but we only kissed 3 years ago. Actually, we haven’t met for 3 years because we are mile apart. But, we have kept in touch for 3 years.

A guy already introduced me his mother. his family speak Spanish, so I couldn’t understand what they talked.
