Accept reality and consequences as your first baby steps.  Then, allow God to help you get to where you must be.  

You know what, sibling rivalry exists, in every family.  Rivalry exists in the workplace, in every day life.  God knows how to help us nulify discord with harmony.  Have a talk with God for further instructions.

First, we are all flawed.  That's our design.  We are also given choices and those choices work in our favor when they are following what God wants us to do.  That, in a nutshell, is maturity.  

We all have lapses in judgement and those poor judments always lead to disappointment.  God is your single most powerful source for moving away from disappointment.

The quick answer...yes.  IF you follow that with a conversation with God.  Disappointment hurts.  God can help you heal.  It's true.

Immarutity is a stumbling block for making good decisions.  It's uncomfortable and most always puts you in a bad place.  Maturity is just one place in your life, it's every place in your life and it is a life-long pursuit.  God can help.  Just ask Him.

A lack of maturity equates to failure in a long-term relationship.  God is a perfect place to start that conversation.  Try it.  It works.

Love, joy and peace.  Did you know that's what God want's us to discover, experience and enjoy in life.  Surprised?

Ever hear the term, "grow up".  Here's how it works.  Sacrifice, suffer a bit and have an attitude that tomorrow will be better because today, you learned a lesson.  Ouch, but necessary.

Success in a relationship is not always easy.  It requires both of you to share similar values and a focused vision on the future.  Communication is at the key of making that happen.
