How close were you and him before he moved away? If you were good friends, then I think you should give him a call instead of telling his mom. Maybe you could even get his address from his mom before he goes traveling and write him a letter. My ex-boyfriend, but best friend still, move and I wrote him a whole notebook and gave it to him when he visited. He loved it. You could keep it casual, sort of like catching up wth an old friend and stick it in there too. If telling his mom is all that you can do, like your last resort, then I say go for it, but if you've got other ways of it being straight from you to him, I think that's even better. Good luck
