Love?

What's your definition of love? Or your perception? How do you know it's love? Examples?

Just curious because some people think that staying in a domestic violence relationship and getting over an incident just for it to happen again is love because they stick it out every time incidents occur.

Others believe sex is love and others believe it's a feeling that you just know and so on.

So I would like to know everyone's love as they perceive it on this app.
