• He gets 'serious'
  • He also goes to the extent of getting 'engaged'
  • Then immediately dumps them

And it's a cycle all over again. He's the definition of a pathetic and narcissistic loser.

Ladies, I think we should ask potential love interests, early on, if they had any ex or in a more subtle way "How would you describe your exes?". In the first case, he could and would lie but hardly in the second one. It is a matter of pride for most men. They parade their list of romantic/sexual partners.

Now, if he lists more than 2 partners, with not much time gap between them, you gotta RUN. Nothing screams red flag more than a guy who doesn't have any sort of stability in life. Relationship stability indicates a lot about his other aspects of life and it also means, he has deep-rooted mental health issues, which is a no-no.
