I helped a friend get a job he wasn't qualified for. He ditched me because of his cheating wife. I became more successful after and have never talked to him again.
That's a very sad story and I was wondering, do you think there's something wrong with him for behaving that way?
There was nothing wrong with him, I just cut him out of my life. He's no kind of real friend for me.
The relationship you had with him sounds toxic. It's good that you moved on and stopped talking to him.
I can't believe he didn't talk to me after that.
Well, people with malicious intentions will make you feel surprised about their motives, but it is probably for the best that he's out of your life now as you won't know what other surprises he may do if he's still in your life. I suggest that you interact with people that you trust and have a lot of history of being trustworthy and respect towards you.
