I have a similar experience to you. You can't change other
people but you can find out what it is about you that is
attracted to people like that....even if there are no visible signs...You may be drawn to their "shadow"..some unhealthy part of yourself that is attracted to the unhealthy. Since you have been the only "constant" in the situation, it's time to look at that. I went to counseling to try and prevent from being attracted to unhealthy people. I learned a lot about myself and also was able to see red flags immediately versus being ignorant and naive. Naivite is cute when you are 5 but it's very ugly when you are a grown adult and trying to have
discernment in dating and marriage. Find everything out about yourself and your past and soon the hidden messages of those you meet will be revealed in that as well. It works.

Yeah, that's my point--they were both nice looking, conservative, Godly women from good families. Tell me Karnak, what features shall I look for now? Homely crack whores?
I don't buy that dopey new-age crap. 'Sides, how do you account for mental illness in the case of the second?
