Guys, Do you feel bad when you upset a girl?

My one guy friend upset me and I think he knows it he never saw me cry or anything but I haven't talked to him in about a week. Today I saw him at work we made eye contact but I didn't say anything to him or look at him after the initial eye contact I did say hi to his coworkers since I know them too. I saw out of the corner of my eye he stared at me when I was walking out saying bye to everyone but him. I know he knows he upset me but I can't tell if he feels bad or was confused or really what's going on.
