J, I agree, get out of your own head. WHy are you analyzing this so much? YOu like her, she likes you, you are building, what are you worried about? Enjoy yourself.

I seriously don't know what person with young children to care for and full time jobs have time to date multiple people. I sacrifice a lot to date one. Dating multiple at once? Seems nearly impossible. Unless there is nothing in between and you are just simply going on dates when you happen to have a free night. But why when you are building something with someone would you want to give your free night to some other random girl?
