The first thing you can do is… Not post that on Facebook. It’s public, everyone can see it. You don’t know what he/she will think when they see it.
Second… Well, I thought this was obvious — just be yourself. If they don’t
like it, move on. Life is too short. There’s way too many fish in the sea.
Third… If you “think” you are “in love” how could you be in love? You feel love. You can’t love with your mind — unless you’re in love with his/her image.
Lastly… Are you looking for love? Do you have a deep desire to love/be loved right now? If you do, the chances are this is — all in your mind. Love happens when you least expect it — when you aren’t looking for anything.
