I'm like this. I fucking hate people. I don't want to be around them. I find so many things they do annoying. Being around others for too long makes me irritable, anxious and exhausted. But some part of me is hard coded for human interaction. If I'm away from people for too long I get depressed and lonely and crave companionship. Once I've spent enough time around someone I've had enough and want to be separate from everyone again. Usually 1 day a week where I have a lengthy interaction (3 to 8 hours) with one or more people is ideal for me. 2 weeks without interaction and I feel like shit, more than one day a week and I start wanting to not be around people when I am around them. I don't think anon is sexist. But they should probably be honest with their girlfriend. Maybe they'd be happier in a less committed relationship.
