Keep in mind that this guy fell in love with you based on who you were presenting yourself to be on the dating service where you were matched.
Since you love him too, all you want is for him to look past the false information you provided on your dating profile.
Nevertheless, that is not realistic.
Irrespective of how much you two have fallen in love since you were matched on the dating site, he fell in love with the person you portrayed yourself to be.
Making this proposal is far too premature, as it is solely based on the butterflies she gives you, which is never how anyone should go about choosing a lifelong mate.
There is a huge elephant in the room; you have never met her in person.
Online dating starts with a digital interface.
Everything you think this woman to be is based off of what you saw on her profile on an online dating site.
