Falling in a one side love, as I said, is a wonderful thing in my experience. You wake up in the morning, and even if it is raining outside, for you it is the sun shining out there. You walk every step with their image in your head. You do many things that you have never done before because those are their things, and you enjoy doing them. You feel the love is filling in the air, having the shy little smile when your friends make some fun out of your love. Those moments are perfect, so enjoy it as you still can.
One side love comes with pain, failures, and disappointments, but it is love. You cannot run away from love. Let me be honest that I have one question in my mind when I am typing these lines: do you seriously consider the fact about the other side’s feelings before you decide to fall in love with them? For me, that is weird. If your heart does all those calculations, then your “love” somehow would be some type of emotions investment - you only give when the others want to do the same. I think there is no need for calculations in love - let me just solve the equations for you:
1 = 2. You can love them enough for both of you.
You do not have to think about ethics and all that kind of stuff. Seriously, just love until you cannot do that anymore. Do not ask yourself over and over “Do I really love them?” or “Is this right?” - there is no point of doing so, as it would likely to only make you feel arbitrary and will never be sure about love.
Be strong and be brave when you fall in love, and stronger and braver when you love them one-side.
Love you all.
