Broken relationship

We start loving each other with everything we had,no love can compare to the love we share but some how one day things started falling apart she wants to be married at 20 and I am just 21,it hard to believe we broke up because it didn't work out the way I wanted it to be, what I want is to get married at 30 an we both can start having kids of our own but she disagree disagree with all my idea,I don't regret it I learned from it,my greatest heart desire is to find another true love
