The other day I was talking with a friend who seems to go from one bad relationship to another. I said to him, "Do you know what your problem is? Your picker's broken."
A lot of people's pickers are broken.
Neurologists say that when you are in love, your brain releases endorphins which create a natural high. I have a friend who says if we were not drunk on love, no one would ever get married. Sometimes the high prevents us from seeing clearly. We can't see the obvious flaws which will poison the relationship because we are drunk on love. Only when romantic love dies down and the endorphins stop kicking in will we see the problems.
If your picker is broken, get some objective counsel before you get too deeply involved in a relationship.
