It's Friday night and you're fucking alone again

I literally have zero fucking friends. I started dating this girl two weeks ago and I think she's starting to realize that I'm a fucking loner autist

Downplay it. Status is what women, all women, look for. Height, money, looks are all essentially only important in so far as they provide higher status. Higher social standing. Jew movies say that women like the mysterious outsider but that's laughable rubbish. At most they'll put up with someone who can have high social status but doesn't bother.

Don't talk to her about being a loner, pretend to be busy if you have to.

You are not supposed to get into a relationship if you don't have any friends or an interesting life to share.
Stick to fwb's and see them no more than once a week. It'll be better for you.
