Oh boy, do I relate with this one. Pure empathy, Here. I think the expression, "You have to love yourself before someone can love you." springs exactly from this very feeling you've described so well in this vent here. I really hope the best for you, and I hope that you can recognize that the love around you and inside of you can trump everything else, as long as you keep it in mind. This person clearly seems to want to be with you :)
Learn to just be of the moment.
Good luck and very nice ending.
