Do you think he felt guilty?

My guy friend and I had a disagreement and it caused him to say some hurtful things to me. We haven't talked in weeks but he bumped into me and a friend. He stopped and spoke to my friend but didn't say anything to me the whole time. I felt uncomfortable with him standing there that I didn't even look at him once but he seemed relaxed. They spoke for about 5 minutes before he left.
