<human>: Can you give me a shortened version of the text?

So, where to begin, we've been friends for years and to say the least we were both very much supportive of another within each of our own endeavors; sure we'd throw the occasional joke around but at the end of the day we'd both know that it was just that, a joke. Though, it was just last year that we decided to join our local gym to 'fit' ourselves up. It was great in the first half of the year, we were still pretty much the same people we were before lifting; but then somehow completely out of nowhere you decided that you'd throw away anything relating to the great person you used to be. You went and got a haircut and literally that was where it all changed. You made some 'gains' and you're ego soared through the roof; now every time we'd hang around our group of friends and during our conversations with new people, you decide that you're more 'alpha' than me and decide to oppress me with the 'jokes' that we'd used to throw around. Honestly now, it is blatantly obvious to both you and I; that you're indirectly attacking and embarrassing me- attempting to conceal the insult under some sort of illusion of a joke and your post-insult "just kidding man". I'm quite sorry to say that you're not the same friend I met awhile ago; and I can honestly say that all your insults really do hurt- come on man, we used to be wingmans... You really think lifting a couple weights, smoking some substances and drinking underage makes you a better person than me? It doesn't give you any right to say the shit you do, and you probably do realize that I only put up with it because we used to be each others 'bro'; yet you continue. But now... what can I say, bro? Our friends will look down on me for ever saying this to your face, they don't see the way you've changed; all they see is the 'mad alpha that lifts' at hand... And honestly I'd really rather not know what happens when I do; perhaps I should just leave the group, I'm sure that world has so much more to offer than egocentric, narcissistic dipshits like you.
<bot>: Friend joins Gym, becomes a dickhead, attempts to enforce his 'alphaness' on me, I'm done being 'friends'.
