Is it normal that i basically just use people?
I'll try to keep this short. The situation is : I don't really have any empathy, so i don't feel anything for other people. Even when i make a mistake that hurts somebody, i do not feel sorry at all. Just a couple of days ago i made my friends girlfriend cry, by making a joke, that wasn't insulting or disrespectfull in any way. They were both pretty mad at me, but all i'm thinking is that she totally overreacted and i don't get what's her problem at all. I'm often in these kinds of situations, because i have a hard time recognising when something goes to far or so.
When something like that happens i, of course, apologise prefusely, and try to make everything good again, but not because i'm actually sorry. I do it just out of self-interest.
For example : I apologised to my best friends girlfriend because, if she were mad at me, we three couldn't hang out anymore, which then means that he'd have to split his time between me and her, which would cause us to see each other less. And even seeing my friend i JUST do because it's "entertainment". I have fun when i'm with him. How he feels, doesn't really bother me.
Is that normal?
