I could lend you one. Middle is smart but all over with what he's doing. Comes complete with a three year old and an ex with huge mental health issues. He isn't dating right now as he hasn't figured out how to get a mental health assessment on random people
I always said my requirement for re-homing a child would be whether they could cook and clean.

No freeloaders!
Tell him online dating is a no-no. All the weirdos I have met have been online.
Volunteer. At church, or the Legion, or at a food bank. That's where you meet nice people, and can figure out if they are nuts or not far earlier than having to go to the 'bathroom' in the restaurant and just continuing on out the back door. Sometimes the people aren't the dating type, but they might have daughters who they are perfectly willing to set up with a nice young man!
