Why am I attracted to substance abusers and borderline personality disorder?

[melisa]

Hello
I would love any feedback about why most of my partners have been substance abusers and or people with borderline personality disorder (psych. problem involving impulsive traits, intense moods, rejections and fear of rejection, etc).
My current partner has both. Astrologer 50 has written that
When looking at a woman’s chart the type of man she would look for is her sun sign and mars traits, plus 7th house planets and house cusp ruler and where that ruler was deposited.
That's helpful. My partner is Pisces-Scorpio-Virgo.
My Sun is trine Neptune, Mars is oppose Neptune, and ruler of my 7th is in my 12th house====those would match his Pisces Sun, and also hint at people with substance abuse or psych. problems. Mars is also oppose the Moon, perhaps indicating emotional problems? The ruler of the 7th is also a few degrees away from directly opposing the 7th house Aquarius.
I attached my chart. Any other indicators about why I would attract water signs. or attract sub. abusers or psych. problems would be helpful.
Thank you
Melisa
