Look dude, I think you and I are a lot alike (you stubborn, stubborn SOB you).
So... by default, I kinda like you.
"By the way a small information emotions, feelings can also be controlled, if the person is very strong on the inside, if the person is very logical then it's not difficult to do so."
What you're saying here just boils down to the fact that self-restraint covers emotions as well as behavior. Which is true, but (to me at least) falls well short of "epiphany" level.
Although yes, many people could stand to take this to heart.
For instance, "venting" one's emotions is usually a VERY bad idea, because that usually just amplifies the emotions and makes them simmer for longer.
But, aha! we have gotten somewhere here.
We started at "incapable of love". Somewhere along the way, when you weren't looking, someone slid over a couple of pawns and a bishop. Now the board looks like this:
"feelings can also be controlled; if the person is very strong on the inside, if the person is very logical then it's not difficult to do so."
Yeah, you presented this as "information", but I know how people like you (and me) think. If you thought this was irrelevant to your own situation, you wouldn't have said it.
So ON SOME LEVEL you are thinking in terms of DEFENDING yourself against certain emotions.
Which is pretty much the most normal thing in the whole world, by the way. I don't see anything weird here at all, except for the bluntness of your writing. But I've never had a problem with blunt.
In any case.
Look dude, I pretty much approached "love" EXACTLY the same way as you did. (Sexually we're polar opposites, but that is not relevant here.)
I pretty much spat on the whole idea of it. Me? Nope. Not gonna.
Don't feel like writing a long literal story, so here's a parable. (A fuckin' parable!)
My heart had a big wooden door that was already locked. Men came and picked at the locks. They didn't succeed. Even so, I pulled my hardest on the door, just in case. Just in case they got through all the locks. They'd still have to out-pull me.
Then one day a man came along who smashed through all the locks. I was scared. I pulled on the door as hard as I could. I'm a strong girl. I pulled that door toward me really, really hard.
He turned the handle and the door flew open...
... inward. Sending me flying into my own walls. With my own damn strength.
Think about it for a while.
