@Liam no i have been fortunate that I have never really experienced bullying. I am a confident person and i hope that this is seen externally so perhaps thats why people dont feel like they can gain the upper hand lol.
No one should be made to feel inferior or be bullied. You have to wonder what troubles this other guy has going on in his life so mich so that he has to project his negative feelings onto others.
Countering his body language will help but just compartmentalize him away in your mind of insignificant things! Stopping even thinking of him will make you feel better!
Like you i had trouble with dating as 5 yeara ago o found myself single for really the firat time ever in my adult life but studying body language has genuinely helped.
