I've got just only question: Why does this thread exist? Love is private feeling, why we have to discuss it right here?

A lot of private feelings are discussed here. Anyway I don't think love always needs to be private. Why be secret about something so awesome? People are allowed to talk about there love. As long as they don't bore us and shove their happiness down other people's throats.

If you or anyone else isn't happy, get someone to close this thread! I don't mind at all, I was being curious.

It's only a private feeling if you want it to be private. And those who do not want to fully express themselves will not post their feelings. Thus, this thread is not compromising anyone.

I see sometimes only as a dependency.

This is not a "discussion", so it is in the off-topic section. We're just stating our opinions/experiences about it. If you consider your point of view about love something private, just watch.

Everyone has personal and different opinions on love

Not everyone has different opinions on love. It probably wouldn't be too hard to find examples of people with the same opinion.
