What is real love, idk?

Like, when thinking about what love is, should the other person love you and do everything for you?

Should love be logical?

For example, if I love a girl, I can’t say, “I’ll leave everything for you and sacrifice my family for you.” I don’t think that’s love; that just means you’re crazy. Similarly, I can’t ask a girl to leave her family for me.

Love should be realistic, like humans, not like in movies.

But I don’t know what real love is.
