but Jennie, you don't KNOW why.
you're guessing, and getting frustrated because you seem to be thinking it's about you somehow.
but it may simply be about HIM entirely.
while you're spinning out possible reasons, how about this one: he's gone back to drinking and doesn't want you to see it?
no reason for me to suppose that's so; just saying maybe you best straightforwardly ask him why he doesn't want your visit....doesn't sound like you'd have much to lose at this point.
