I asked her why this is so because I thought that was a bad thing but she told me that at least with a possessive and jealous boyfriend, you're sure that he cares and that he's paying attention and you guys will always be together because he always pops up everywhere.
So you want a mentally unstable bf who might abuse you too because they have uncontrollable jealousy issues? Go for it.
If you think jealousy is a metric of a healthy relationship, there are not enough drugs and therapy in the world to help you.
I have a long time interest in psychology, specializing in relationship dynamics for 30 years.
