Why is he upset with me?

In the meeting with the group we have a project going, things were discussed and it hit my p and I ran out of the room crying. One of the guys ran after me to comfort me, I stayed in the hall way trying to calm down this guy made sure I was alright. Then had a group of people around me they were concern, so I missed most of the meeting. My friend who has crush on mel, I think was over the meeting, well he was angry with me for what I do not know he did not talk to me the rest of the day. I know he likes to be the center of attention most of the time and that day i was. He does not like other guys t alking to me and that particular guy who ran after me in the hall way was all around me the rest of the dayt he just concerned making sure I was alright. Or I know he really depends on me especially in the meeting I am always there to take care of business and help him, this time I was not, I was told by other people when I am there with him he is alright when I'm not There he panic
