Try having a spine for a change. Don't spend every waking hour around, on the phone with, or tailing behind your lady. Get some friends for chrissakes. Saying it every 2 seconds is not. Rule 3 goes double for crying.
Some women have very complex psychological problems.
Same said women are beyond your rehabilitative capabilities. Save your attention for someone sane enough to appreciate it. Never EVER assume that a second date means that you're hoplessly in love with each other. It just means that you are not a rapist, stalker, blatant chauvinist, or completely unattractive. Get real, get over it, and don't let it happen again.
