OP, I've got news for you. The only way you'll ever really know if she is the wrong woman or right woman is once you've committed. So many woman do 180s a few years into the marriage.No I completely agree that fear of commitment is a real thing for men, but agree it's mainly due to fear of the wrong women (in my own experience).
I don't think I have time to work this all out and I should just cut her off and go no contact, she's still going on this date tomorrow so it's making my decision easier.
So thinking you are going to know prior to being committed is a problem because you won't.
Not saying you should commit to this woman, just saying that you'll never truly know until you are committed and see if her actions change once that happens.
