I do understand that feeling. It's quite common now, and to some degree has been for a long time.
Sometimes its hard for a woman to open up to herself how she feels...maybe she has certain expectations.
When I was a younger fellow I gave too many chances, too much "benefit of a doubt". One thing I've learned is that you have no control over someone's feelings, their prior or present experiences, etc. So, live life for you, with the Lord as your guide. Go into dates, etc with the attitude that you are getting to know a sister in Christ, or possibly of the world....don't take it seriously. Kind of, treat her like a little sister. Show your happy playful side, be lighthearted. But don't lose yourself in the moment. You're just getting to know each other. If it doesn't work out, consider that maybe you have just dodged a bullet. I have dodged several...lol!
I know this is a tough thing as a young man, women have no idea how we think about dating, and I'm sure they would say the same for their fellow women. Try not to take it all too seriously. There are plenty of books on this subject, do some looking and see what feels right for you. This decision you make, the possibility of who your life partner is.
