YEP!

Perhaps you are opening up in a way that is frightening to a woman? i.e. past history of mental or physical abuse to an ex? (I'm sorry but I probably don't care how sorry you are or how much therapy you've had) Past criminal behavior ?(I would bet 80% of women would not want an ex-con in their lives, especially if they have children.) Past history of instability? (I want you to be my rock and I'll be yours).
I guess what I'm trying to say is yes be yourself but you need to paint your picture as one that another would want to view. If you paint with black and orange and I hate those colors, I won't look for long. Bad metaphor...sorry!
