My advice is to leave her alone until the date you agreed to meet.
I encourage you to continue reading relationship type books. You need to learn how more about how women think/feel. And, if I may point out a couple of things, I think it will help you in future relationships.
Stop with the jokes and teasing, b/c they are not funny. They are painful to women. Never, EVER tease/joke about any part of her body. Even if she has a good sense of humor, don't tease and joke about her body, her family, etc. So many men have killed a good W's love by this type of carelessness...….and they call it "teasing and/or joking".
The same applies to children. Whether it is your child or your step-child, he looks to you for support, security, and protection. Build him up. Don't tear him down.
You are able to change for the better, by learning the skills to have a good relationship in the future.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
