I decided to drop a friend of 15 years this year, there were some things that became 'the final straw(s)' after their desire for success became too much.
This person was always a bit self-obsessed and thought they were Gods gift to the opposite sex, but that was just part of them and I could live with that. I think they just thrived on attention (which may explain the fiasco when they told me about my 'suprise' birthday party that my DP was planning). For someone so academically smart, they made some really dumb life choices especially with partners, I.e. picking unsuitable partners, or when they did find someone nice, cheat on them (they knew I'd been cheated on, so I didn't agree with this but everyone makes mistakes).
It was when they changed 'jobs' and joined a MLM they jumped into this with both feet wholeheartedly and took their desire for success to a whole new weird level. Tried to recruit me repeatedly asking my opinions on what technique I thought might work with chronic illness self-help groups etc. So each time I mentioned something at work that was a bit challenging, it was met with a response of "come work for me, your life will be so much better being your own boss". So I felt couldn't talk about that. Ok, so talk about my family "you'd have so much more time with them if you came to work for me".
. They worked very hard to project this image of success that I knew was BS - the MLM didn't earn them their car, an inheritance paid for that! The MLM didn't pay their mortgage, it was their parents house! And on it went...
Even when we were close, they made me feel bad for 'how long it had been since we last met' following on with PA remarks about how they know I'm 'always busy with family'.
I started to distance myself, but they'd contact me in a flap about their latest relationship disaster, so I'd listen and offer advice. Then they'd get round to asking me about my life. Again, the usual responses. If I mentioned my chronic pain condition, I'd then get:
Friend: "you should use my product. I think it would help you".
Me: "That's interesting. (Yawn)"
Friend: "my neighbour had the exact same symptoms"
Me: (but your neighbour is male, so no, not quite the same)
"oh, I'll look it up on the Internet"
Friend: "I'll send you some"
Me: "uhh, maybe send me the information on it?"
Friend: "I'll send you some, but promise me you'll use it. It'll be a gift for you"
Me: "uhh, I'll show the info to my specialist, see what they say. I'm seeing them in a fortnight (lie)"
Friend: "contact me when you need it. Don't buy it from anyone else".
Me:

No interest in the hideous effect the condition was having on my life or me as a person.
Their 'business' wasn't doing as well as hoped this year, as they then changed their f/b posts to 'extra extra motivational' memes, berating themselves for not making as much money working hard enough. In these posts included gumpf including tripe about how "anxiety was only worrying about the future, depression was only worrying about the past"
. Other tripe about "those around you try to hold you back because they can't admit that they're still left behind where they don't want to be" and PA comments about those who didn't believe in the MLM model, how we're jealous etc etc.
I've unfollowed them on f/b and have let it fizzle out. Such a shame that in the end, they only saw me as an opportunity to make money.
