I was wondering how do you know when dating turns into a boyfriend/girlfriend relationship??

I always thought that by getting to dating, one was already in a bf/gf relationship

The time when you can't stop thinking about each other is the time you should know you are in love . Talk to each other and get to know your relationship better.

When you know each other well enough, to just be exclusive, and date no others, by mutual agreement.

By verbally committing to it. Dating someone doesn't make you their bf/gf.

When someone ask you to be his/her bf/gf or you ask them

If one is girl and the other is a boy...
And you are friends, what does that mean?? You don't call that love. Love comes after a friendship has been established.

When the air is cleared and the title is clearly defined by both of you.

I don't really see a point to rush to the "titles" anyway. Dating is supposed to be fun, so, please, no overcomplicating it...
