I think that in the early part of a relationship, we sell our good side and then later we learn about the other side (dark side) of that person, the Burping and Farting and Nascar come later :) oh and whatever other flaws there may be. I think that it is just human nature to hide flaws.
Love really comes when you love everything.. and when you can love yourself for your own flaws too.
I haven't accepted some of my flaws either.. you are not alone.
