''You're the love of my life''
''You're my soulmate''
''We're meant to be forever''
You're going to dump them anyways so what was all that enery, talk and time spend for? It doesn't make sense to be someone's ''soulmate'' but only be their temporarily girlfriend/boyfriend that can be replaced any moment. There is nothing holding you together without kids... nothing. Total waste of time. Too much for nothing.
