You think about him/her all the time. You crack a smile whenever you think about this person. You have feelings of elation and joy and you can't wait to talk to them. You find yourself thinking about them before bed and when you wake up. You can't imagine your life without them. You get butterflies in your tummy. This special love takes you by surprise and knocks you off your feet so to speak.

you'll know 100% when you're in love. If you're unsure then you're not in love.

You find yourself thinking about them a lot and they preoccupy your thoughts more than anything else

When his emotions begin to impact my emotions, when his sadness makes me want to tear the world apart to find him some happiness, when his happiness makes me feel like I am on a cloud, when I begin to feel like I am losing control over myself taken over by someone else. When I begin to think of the impact on him with all my major decisions. When he becomes a part of my life in the most natural fit.

You anticipate their presence

Don't ask me. Whenever I thought I was it was lust. And whenever I thought I wasn't I pushed it away and realized later that I was.

I feel it in my fingers
I feel it in my toes
The love that's all around me
And so the feeling grows

I wish I knew. When you find out, please tell me. I'll do the same for you.

Empty bank account

I can't really describe it

Not that much. Lose sleep. Lose your mind. No big deal.

You grow horns

Suddenly life has new meaning. Things become magical and anything is possible. You notice things you did not before. You wake up.

LOL

One goes beyond crazy only when starts loving.
Few steps ahead of your present query.

You just do....it's unmistakable

Their happiness is what comes first

You just do.

Idk either

I urinate a lot more

You start doing dumb shit

You understand the other person is not perfect. They can get on your nerves and disagree but you still want them with you. When they are away from you they are on your mind. You can’t picture your life with someone different

Same way I know I'm cold. You can't miss it
