I have to say, you've received some very good responses here...
I wouldn't let some posters upset the apple cart or cause less doubt in my own self esteem...besides, haven't you ever had a crush on a teacher, movie star or rock star? Sometimes that crush you feel is what you believe that person is like inside. Then you hear they've just opened their mouth and embarrassed the entire man race with something unintelligent and really really insulting. Changes your entire feelings for that person, doesn't it?
True Beauty is happiness and good will welling up from within...also, giving it's owner good health and an aura which shines...
I wouldn't doubt the woman in you, in the least, but what I would do, is make certain your boyfriend deserves you, is compatible with you, caring, and supports your ideas and opinions....not to mention, allows you your identity, without trying to change you, loving you for who you are and what you represent in his life.
And, deep down inside, I believe you already know the answer to that question.
