Natural compatibility trumps compromise!
If you or your mate has to change your core being to make a relationship "work" there's a good chance you're with the "wrong person". If you or them has to "change" every time one enters into a new relationship it's impossible to find true happiness.
Very few people are walking around with one hand raised in the air screaming: "I'm looking for someone to change me!"
Most people want to be loved and appreciated for (they) are!
The goal is to find someone who (already is) what you want and vice versa. Loving oneself begins with being true to oneself.
