My brother needs his Mam

So this is my younger brother, he's one of the kindest most genuine person I've ever known and would do anything for anyone. On Sunday night he found out that his so called best friend and girlfriend had been sleeping together. They have been best friends for 15 years and even each other's name tattooed on their wrists. He had been with his girlfriend for over 4 years and live together. I have took my brother into my apartment and and trying to help him out but all he wants is his Mam. We live in Canada and our parents recently moved back to England to be close to the grandkids so it's just my brother and I here now. He goes to school full time in order to make a better life for himself and only works part time because of his commitments to school, and he can't afford to book a flight home. I would love to book him a flight home asap so he can be with our Mam and just the comfort that a parent offers, the lad has suffered the ultimate betrayal in my eyes and it kills me to see him like this
