people with BPD are like anyone else in this regard. some people have a clearly defined "type", some people dont.
a person with BPD does, usually unconsciously, look for someone to complete them. however, one could say the same about a great deal of the worlds population (i hear it from my peers ALL the time). BPD traits are human nature taken to extremes.
for example, as an introvert, im often attracted to extroverted women. not necessarily because i want to be an extrovert, but because its often a complimentary match.
And then ‘blaming’ for being that way because he is not?
people in general pay lots of lip service to ideals during courtship. theyre on their best behavior and want to be an attractive choice. it sounds like he praised your independence (it is possible that he envied it, i dont know him well enough to say) but his insecurity got the better of him.
