It’s not a feeling you can describe. It is totally different for everyone. For me it is trusting someone with your life and being faithful, honest and true to them. It is doing anything and everything to make that person happy and making sacrifices of yourself. It is believing in that person, compromise and conversation. When you look at them you fall in love all over again. You don’t care about what they look like, or anything. They aren’t only your boyfriend or girlfriend, husband or wife, but your best friend. You get physically ill at the thought of not being with them. It is a force that takes over you where you feel completely happy and fulfilled. It is an amazing feeling, but it can also ruin your life. Either way, it changes your life. For me, it is the greatest feeling that you can have.
