To invite my cousin for Christmas?

[pattypatta]

My cousin is 38-39 and he hasn't really visited in over 18 years even tho he lives in same city.
My uncle (his dad) and mum (my aunt ) died last year before Christmas.
He is an only child and still lived at home,painfully shy and no friends really.
I don't have his address or phone number but he goes in the city centre post office where my friend works.
In January I told my friend next time he comes in give him my phone number and tell him to call or text me if he wants and we could have a chat or even meet for a coffee.
Anyway he didn't call.
Now it's nearly Christmas and it breaks my heart to think of him alone.
Aibu to ask my friend to ask him again or do I respect his decision that he wants to not meet up?

You sound like a lovely caring person. Would you be able to find him on Facebook etc and get in touch one more
time explaining no pressure but just putting it out there that we'd love to have you over for Christmas if you would like. I wonder if perhaps he's so shy that is unsure how to initiate the conversation or is perhaps still overcome with grief or loneliness and might need some help talking.

He is very shy,he was so close to his mum and dad,went on holidays etc.
The thought of him being upset at Christmas upsets me even tho we are not close.

Could you leave a Christmas card with your friend to pass on if she's in.

I'd word it that you'd love to get back in touch here is your number, if he's free at Christmas you'd love to have him over.
