Love is when every organ in your body feels like it will leave your mouth if you ever lose this person.c

You will know. Just relax and enjoy each other anyway. There's really no need whatsoever to put a name on it, people rushing to do so are usually doing so out of some sort of insecurity.

The biggest piece of advice I think anyone dating should receive is to make sure you don't let insecurities overtake you. A lot of relationships seem to die because the two people involved push each other apart over their own insecure behaviours.
