How can I kill my "ego" when it comes to dating? When things are going well with a girl I'm really chill and actually don't really think about her. When things go south though, I get really emotional. I get scared of losing her which really puts me down and I start thinking that I have deep feelings for her. This doesn't of course happen with every girl I date, I've gotten ghosted many times and couldn't have cared less, it happens only with the ones that I've spent a lot of time with.

Is this some kind of fear of rejection or something?
