By Thomas Merton? - The beginning of love is to let those we love to be perfectly themselves, and not to twist them to fit our own image. Otherwise we love only the reflection of ourselves we find in them.
A thought... A reflection of ourselves is basically what we identify as soulmate, having someone like you who is perfectly made just for you. But the fact is nobody can really be truly be made for us as we have our own choices of who to love and who we choose therefore whoever you end up loving shouldn't be loved because they are like you but because you like them in ways they are different or similar to you.
