I'm the opposite, but similar, in its not natural for me to know,so i get paranoid and leave early.

Probably because my dad doesn't understand social queues, he would visit relatives daily and stay for hours, until they started hiding from him. I also had a friend, who practically stalked me when I was 9, looking back I think she was being abused,and wanted me there as a shield.

So I worry terribly that im over staying my welcome. When I met a guy, who suddenly, over night started acting like I was a pain to be around, it was torture! He would look at his watch at 9pm, and say I should drive the 40 minutes home. He complained that I kept a toothbrush there (had for 6 months at that point) He told me to get a teenagers job on Saturday, so I wouldnt bother him.

As someone who is hyper sensitive about not intruding or bothering anyone, it was just awful. I even asked him to tell me if he wanted a weekend to himself, but he wouldn't. He would just let me turn up on saturday night, then make passive aggressive digs.

To add extra confusion, one time I left early, and he asked if he had upset me. Argh!

Two things i am paranoid about, someone pretending to like me, and being a nuisance. And he triggered both.

Then I bounced on to someone who wanted me with him 24/7. So I'm now very confused. In social situations I try to set a goal time to leave, but it's still something I have to think about.
