remember this: when we act like we don't love, that's when we need your love the most.
my fiance and i went through the same thing this year. i had three family members to die, my dad got cancer and i lost my job. it was during this time that my fiance had to step up and be a man of God. he had to cover me in love and grace. he had to constantly show me mercy.
maybe instead of praying that your relationship is regained, maybe you can thank God that He has put you in a place to show His love to a sister in need. maybe you can pray that God will use you to be an example of a constant in her life. (everything else is not steady anymore. everything she knows is surreal now.) and as far as harrison goes, that is truely in God's hands. you may have to be her confidence now... now she needs you more than ever!

Please be patient and trust in the path the Lord is leading you on. You are in my prayers.

Your friend must be in dispair and really needs your help. But now she may pretend to reject it. May Goe heal her hurt mind and recover her.
