girlfriend.

What is her opinion of what is happening? Has she offered any suggestions
for how to win the cat over? Does she seem sympathetic to you, or does
she think it's your fault her cat doesn't like you? Maybe he's being
territorial/jealous about your girlfriend?

Does he also jump on her in the middle of the night? That is, is this
just something he does, rather than something he does to *you*? Some cats
can be a nuisance in the middle of the night - they want attention, food,
to go outside, or whatever, and will think nothing of pawing, nosing,
jumping on, or otherwise bothering the sleeping humans. (One of my cats
stands right next to my head and yowls when she gets the idea that she
must go out in the middle of the night. This pretty much always gets her
removed from the bedroom with the door closed. So she doesn't do it very
often any more.)

I would suggest you talk to your gf about this if you haven't already.
Ask her how she feels about keeping him out of the bedroom at night. She
might surprise you. And if she doesn't want to do that, you're no worse
off than you are now. But I think you're entitled to expect *some* kind
of support from her, at least in terms of putting your heads together to
figure out what can be done.

How long has he been acting like this? Since you first started dating?
How long has that been? Just wondering if this is part of a phase where
he is just getting used to you, or if it's been going on a long time.
