ok this thread is totally clear,
as you where sponsoring him you have to for 3 years give him,
- an adequate place to live
- appropriate utilities for their accommodation
- adequate food, clothing, household supplies and personal requirements for day to day living
- Dental care, eye care and other health services not provided by public health care.
- financial assistance to ensure financial support is not required from any federal or provincial assistance program.
and as it states in the letter you have to support him even if he is unable or UNWILLING to support himself.
This has nothing to do if his dad or someone else has money or not, you signed this all so youre resposible for him.
as clear as that.
on another note, yeah its sad if things don t work out, but if you break it up that easily you have to take resposibility for your actions.
cheers
