So just being madly in love isn't enough?

I think most of us would like to believe that a successful relationship is base on being in love (giving, receiving and exchanging limerance) but is that really enough?

If so, then wouldn't everyone in love be having kids with them? Wouldn't the saying ''If you really love them'' then you would commit to them, have kids with them'' apply? Or if they were the ''love of your life'' as you claimed, wouldn't they be your life partner until death? After all the love of your life (since the words ''of my life'' are included) is literally translate to an actual life partner you want to have kids and grow old with.

Yet there are many stories of people in love and keep saying ''oh he/she's the love of my life'' but yet they break up, never had kids nor marry them. So being madly in love (head over heels) isn't enough right? You can have love, respect but no commitment nor compatibilities and those relationships end too. What do you think?

Compatibility... if someone wants to travel around the world with a partner but no kids while the other person wants a family... that relationship is going to fail.

Then no amount of being in love and exchanging feelings is going to solve that lack of compatibility.
