Borderline personalities.
Learn how to spot them.
If you see a woman who exhibts even two or three of these signs, run as far as you can, as fast as you can. Block her, delete her, never ever speak to her again. Cross the street to avoid her if you see her in real life.
They will destroy you.
Borderlines usually exhibit
- self harm
- impulsive behaviour
- unstable relationships
- intense fear of abandonment
- extreme emotional swings
- chronic emptiness
- explosive bursts of anger
- intense paranoia
The quickest way to spot a borderline is how she love-bombs you in the early stages of the relationship, she comes on quick, talks about how you are her hero and how badly she has been treated before. Sex will be incredible and she will use it to control you. But before long, you will see her mean side and nothing you can do is good enough for her. But because you are addicted to the hot crazy sex you will keep coming back for more.
Eventually she will go full psycho on you.
