Find out from him what he wanna talk to you about, and whether
if it's possible to just talk about things over the phone?
Note what Yun has mentioned also. And if so Yun is right about the
information and 'feeding' part. Realise that it might not really be
so easy for you to just help him 'get over things' too. If you can
and wish to try, just do what's within your reasonable limit. Else,
just 'pack things up' for him and let him realise he has to face
this fact of 'break up' and adjust by himself or something like
that...?
