Don't put yourself down like that. Love yourself. Make a list of you're best features and what makes you unique that's a good start. Now as for your question perhaps you can keep the friendship open, as you two talk more maybe something will spark :)
Honestly, excuse me for being rude but if you lose some weigh you'll not only get noticed but you'll also feel better about yourself. You'll gain self confidence and want to make your self look "prettier" it may be hard but hard work really pays off.
