CS, one of dp's friends had a date the other week from a web site. I know this is different, but it is kind of a bit similar.
The morning after their first date, the lady texted him and said, "if you're serious about me, I'm going to take myself off the website".
Now, I hope you know that I try to be kind, and I am a lady so I know how we think, but from an outsider's point of view I was like "woah! Not so fast lady, for your own sake". And dp's friend was saying, "cor, that's a bit soon". It did make him back off.
Keep repeating this to yourself "poor sap. He doesn't know how close he is to getting knocked off his feet. Let him enjoy his last few days of freedom" - til you feel better about yourself and less worried about him. If you believe you are fabulous, you are fabulous. Trust me! ((()))
