I got a PM about this last post, and my response was so long that it exceeded the PM limit. So I'm putting the response here:
===============================================
It sucks, man.
But I don't think that alone is enough to indicate BPD. BPD is serious and it's rare. I have spent many many hours studying it before I finally accepted that was the problem with my ex, and that she was a Waif type.
There will be dozens of other indicators. Mine were:
- intermittent childlike demeanor, behavior, voice, tantrums
- hypersensitive
- ultra feminine
- super emotional with wild mood swings seemingly triggered by nothing
- fear of making plans and inability to make decisions
- extreme clinginess and insecurity bordering on paranoia. Constantly needs to see you, talk to you, and wants to know where you are and who you're with.
- feeling like NO amount of affection, affirmation, reassurance is enough
- walking on eggshells in order not to trigger a bad mood
- immediately established emotional intimacy and shared deepest secrets on our first night together
- went to psychics and kept a journal of their "readings", with the intent to find out if I was "the one." General obsession with finding "The One"
- needing CONSTANT contact and being upset if a text or call is not answered within a few minutes or an hour
- black and white thinking such as, "if you can come over by 9 then we can have a great night together, if you get here any time after 9 then the night is completely ruined"
- highly intelligent, yet seemed to lack common sense in emotional matters
- aversion to introspection or questioning of any kind
- gets upset if demands are placed on her or dissatisfactions with her behavior are voiced
- extreme sexuality in the beginning of the relationship which is then withdrawn to a large extent
- she will make you feel like the king of the universe from day 1
- stories, tears, and behaviors designed to make you pity her and feel that you need to save her from past pain
- in arguments, you find yourself giving ground and feeling like you are always at fault, questioning and doubting how "good" you are to her
- depressive episodes (mine once said that she didn't want to live anymore, after she got upset with me and felt that I had blown her off one night)
- strange statements such as "I know now that I'm not meant to be with someone the way other people are"
- conflicting statements and confusing behavior
- you have a feeling that she wants serious commitment, then when you discuss it, she backs away
- a feeling that she is helpless and needs to be taken care of and guided, in decisions both large and small
- real self-confidence issues, and feelings of shyness and inadequacy
- eating disorders (she went on two super crazy/restrictive diets in the period before we broke up... one of them was 500 calories a day with HCG shots). Eating disorders can substitute as a "disfigurement" behavior as opposed to cutting or burning.
- daddy issues (mine had a controlling mother she loved but was fearful of, and a father who had cheated/left the mother, started another family, and barely even acknowledged her existence anymore)
- told me the first night about her baby brother who had drowned whens he was very young, told me shortly after (couple weeks maybe?) that she thought it may have been her fault for leaving the door open
- physical maladies including cramps, frequent headaches, heartburn, always being cold even if it's 80 degrees out, anxiety attacks, or imagined symptoms (she once told me she thought she was contracting asthma)
- many more...
BPD is something that is so pervasive in their behavior, you will look back on your relationship and see DOZENS of clear indicators that something wasn't right.
There is low interest, and there is BPD. Two totally different ballgames. If you cannot find numerous, clear indicators of BPD, I would go with low interest.
