WHY is no one else in his life? Not because he is a victim but because his actions and manipulations have anyone sane get as away as possible, like many of us do here (going No Contact). Perhaps I am just triggered as ex said he was also 'alone' and 'I was the only one he had' and I fell for that $#&&many times and was used, and used again...
I dunno MQ, I read most of your posts since I joined, and I just do not get why he can't recover or try recovering without bugging you or affecting you in some way. Honestly I read your post and to me he seems like he is like another kid to you, not an adult.
A question to ponder, when exactly are you going to stop giving him money? do you have set an exact amount? or is this like "this is the last time you help him financially" just like they say "this is my last drink"...?
I guess... as the 1st step, once you are totally honest with yourself, you'll know the answer for this thread's title...
All the best
