Bit of background: Most of my social circle is guys ive known since high school (age 12-13) or earlier. Until about 17 i was extremely shy, skinny, no confidence, couldn't even speak to girls, etc. I've been steadily improving for 5-6 years (we're now all 21-24) and am now in a very good place. Good degree, well paying job, true confidence in myself (not cockyness), genuine top 10% physique, n-count of 20+, hot girlfriend, etc. (This isn't a humble brag, there'll be people reading this who've achieved far more than me. Just providing context).
I've recently fallen out with 3 guys in the circle for (separate) incidents in which im sure any reasonable person would agree involved them being assholes (won't bore you with the details). I wasn't overly surprised as these guys have questionable characters and ive clashed minorly with them in the past. What they have in common is they're not exactly succeeding in life since we left school. They're either unemployed or working very low skilled jobs, overweight, no higher education, bad looking, no success with women, etc. They are also without question the most dishonest, selfish guys in the social circle.
Oppositely, the guys who I've grown closer with over the years are the guys who are doing well for themselves and seeing success and improvement in life. They are happy for me and I'm happy for them and want to see them do well.
I truly believe the guys I've fallen out with are jealous of my succes (especially considering they were more popular than me in high school, maybe my success highlights their failure to improve) and this has lead to their resentment of me.
I've read a lot on here about the crab bucket mentality (basically, people don't want you to improve yourself as it reminds them of their own failures. Has anyone else noticed the trend of it being unsuccessful, jealous friends who tend to turn on you when you succeed? Just looking for experiences and discussion.
Tl;dr: Improved myself significantly in virtually every way since high school. Friends who have failed to do so themselves show resentment and are arseholes towards me. Oppositely, successful friends are happy for me, and me for them. Is this common on the road of self improvement?
