I was ready to catch, but you weren't ready to fall
The problem with falling in love is it literally means falling. It's like a slow agonising death where in the end you choose to accept it. Falling isn't necessarily a good thing in life. It's always unexpected but always possible.
Falling in love is like falling into an abyss where you don't know the end of it. Sometimes you just have to face it's going to be the death of you.
One problem with falling in love though, your arms are always ready to catch. Whether its a person, a truck full of hurt or a pit full of lies it doesn't matter. Your carelessly open arms are always ready to catch what falls into the abyss along with you with the mere hope that a person will fall too. And it can't just be any person, it has to be that person.
But you have to accept that even if that person does fall, there's a chance they won't even brush past your open arms. Because in the darkness of the abyss, somehow they'll find another pair of arms holding out for them.
