Yes! When someone has paid tens (hundreds?) so that you have an enjoyable time at their place, a thank-you isn't too much to ask. I don't care if their introverted or not.

The OP has already done more than enough to make their so-called friend happy. Why should they do more by accommodating such rude and impolite behavior? It sounds like people are expecting the OP to give, give, give while the friend takes, takes, takes.
