This always happens. Maybe it's me, or something Im doing wrong. Long story short things end up working. We match and start to talk. But after some time, I notice that they go off the rails.

Women I get close to seem to become super paranoid, upset, unhappy, insecure.. then eventually shuts down. I don't understand it at all. Things could be going perfectly at first. Calling and chatting NON STOP. Saying I love you, goodnight/morning, all the time.. but after 6 months they just shut down out of no where or begin to LOOK for problems literally overnight.

Are all women like this, eventually they just shut down and wallow in their unhappiness? Am I doing something wrong? It's like I take the advice from here and actually get the girl but keeping them (sane) is another issue.
