I like what someone else said, that if you have a negative reaction to the situation, if/when he slips up, then you are probably being co/de.
But I also feel that it seems as if the guy is truly trying, and to not give a small leg up would not be right. I can't say if I would help my exah, at least not right now,and maybe not ever, but that is me, not you.
I think you are being compassionate and kind. Just don't get sucked back in. Stay detached. If you can't do that,then you shouldn't help him imho. H
