<human>: I'm sure I'm not the only person out there thats run into this situation before, but I don't really know how to handle this. 

I've known the guy for 15 years and we've grown apart somewhat as life has progressed. Unfortunately for him, he got a girl pregnant at 16 and never made it to college. Fast forward several years, one marriage and two other children, he and his spouse haven't made much money or progressed much in life. I understand why people might want to be involved with Amway as an extra source of flexible income but this is getting ridiculous. 

I get texts that seem genuine enough like "Hey man, how's it going?" that start to lure me into checking in. Sure enough, the conversation steers towards my hobby of fitness and progresses into what proteins, supplements or other things he can sell to me. If I don't respond, I occasionally get a follow up text from his wife (also involved with Amway). All of this had led to me ignoring him, which is not a goal that I have for our friendship.

How can I handle this as a long term friend?

Can you summarize the given text in a few sentences?
<bot>: Friend of 15+ years and his wife are involved with Amway. Every conversation is about selling me things. Help?
