She clearly wants you to be a step-father for her daughter or else she wouldn’t be including you in her daughter’s social life. But, I think she felt disrespected when you wouldn’t kiss her in front of your parents, because she allowed you to sleep over when her daughter was in the house and she felt you should do something in kind. She thought you weren’t taking the relationship as seriously as she was and that there wasn’t going to be the same level of commitment from you that she was showing.
So decide if you want her for good or not, and then show her — by declaring her yours.
I hope that helps. Let me know how things go, and join me @AskAprilcom on Twitter, and on Facebook at this link: [url]
