Am I the bad guy?

I friend zoned a guy because I didn’t see us being compatible in the long run. I agreed to stay friends . And then a few weeks later I start dating again and meet an amazing guy . The friend zoned guy keeps asking if I found someone yet and I say no because he was stressed out from losing a job . I finally tell him I’m dating someone and hes suddenly acting suicidal , he’s back on drugs , he lost his job , and hes gambled all his money away . I feel so guilty . But I don’t know how to fix it .
