Does he interested in me? Or Just lose his mind at the party?

We're not couple, we're just classmate. But we always dance together and hug each other when there is a college party. We are more like a party partner rather than friend. Last Friday night, he hugged me tighter than usual and then pat my head while hugging and dancing. Besides, he intertwine my fingers like a couple ( he never does before). But as usual, we turn into typical classmate when the party is over. I want to know that does he interested in me or just caught up in the moment? Because we both are too drunk at that time.

After that day he asked me to go to the bar with him. Just the two of us.
