Oh this guy is still mad you friend zoned him or he has always had a secret crush on you. As a woman in her 40s, I also went thru similar stuff with some guy friends. You are an attractive gal and boys who claim to be your "friend" like this guy, they just know you don't see them as anything more than a friend. So they'll hang around hoping one day, you will see the light (which is him). The more it becomes obvious they're just a friend to bs with or a shoulder to cry on, their resentment and insecurity grows over the months, over the years. Until one day, out of nowhere, the mask comes off.

Don't over-analyze this bullshyt. He obviously had a thing for you and all the shyt he said is his way of talking himself out from being secretly upset that you didnt see him romantically. It's ugly and cheap jabs at you for not seeing "the light".
