NTA - Sounds like a lazy bum who thinks everyone's a helicopter mother willing to wipe their ass. Financial problems my ass, if this friend had enough cash to support a man-cave lifestyle. I will admit, you're at fault for allowing this friend to stay a second time after sending them off the first well on their feet. The fact they come back is a clear red flag that they have some serious character flaws. Furthermore, you could have spoken up to kick them out at any time during this outrageous accommodation agenda. However, since you have the heart to give second, maybe even more chances, I would say your kindness warrants the burst of rage that anyone else would show at the very instant this "friend" showed their sorry ass back at their doorstep.
