Best friend scammed, now he's back?

Jul 2021
Long story short my friend is from a poor country and I lent him money, he couldn't pay, bailed on me. 5 months later I got in contact and he apologized and explained. Now he says he's working on repaying somehow.

I don't know what to say or do since 80% of what he says is a lie.

I'm afraid I'm letting my emotions run over me and I'll get scammed again
