Hey, don't despair. Do you aknowledge God as God? Do you revere Him as a Mighty One who knows yesterday, today and tomorrow? Perhaps He has a different plan for you, plan to prosper and to give you hope?... Dear one, you can't demand your way like that- will you love Him no matter what? Is He enough for you? Don't treat God as a wish-granter... He loves you enough to die for you and has a plan for your life. Trust Him in your difficult today. He will take care of your tomorrow - just dont get a tunnel vision, keep your eyes open and thank Him - find lots of things to thank Him for right now and daily. With love, your christian family memeber.
P.S. I did go through a loss of a loved one (due to betrayal) with whom I saw a marriage in the future. Feel sorry for your heartache and will pray for GODS WILL for your situation.
