Why does my close guy friend ignore me when we are hanging out with others or around a lot of people?

[Misa Joon]

1. he's shy . .
2. he's socially awkward
3. he's insecure about something to do with himself and in public thinks people
will see it ( i really dont know i this makes sense )
4. he's being bullied and thinks bullies might spot him in public ( that's the worst )
5. he just doesnt like being crowded ( im like that sometimes)
6.he doesnt want other females in public to think he's not single . he wants to look open for relationships ?
7. last and LEAST - he's embarrassed by u in public ( sorry :T ) and wants to pretend he doesnt know u
