I think you should just leave it be for now. He clearly has a lot going on right now in his life. I would leave it as friends and whatever happens happens you know? Let him figure out how his life is going and get his two feet on the ground. The situation with his friend seems really serious but i don’t understand why that would effect his life so much. I understand that if they are super close that it is upsetting but to really be putting him in a depressive state? He should of also made more of an effort to see you before. If he has car troubles there is always a bus like a greyhound or something. I would just ride it out and see how it goes though.
