I fully agree with what Brother Paul, Ceile De, and gonefishing are saying about not worrying and being thankful. When you worry about what may be, you not only live in negativity but you won't be able to see blessings because you are blocking them with doubt and fear. God works through faith in everything in our lives.
The bible says, "everything that does not come from faith is sin" (Romans 14:23).
Doubt and negativity need to be blocked the same way that evil does. "All my thoughts and emotions are washed in the blood of Jesus." The reason you want a particular man is to be happy and feel loved. But Gods way is for you to be happy and feel loved before you get the man. Not only that but he wants you to know how to give love before you get the man. The reason for this is that even if you got a man you "wanted" if you didn't know how to give love and receive love (which often has to be learned) then the relationship will likely end in disaster. If it is God that is going to give someone their husband, he wants the relationship blessed so that there is a true commitment of love between the two people and they are compatible, like they both are saved. God brings someone when they are ready and the relationship can work.
You can have happiness now. A relationship should be a bonus, not what makes you happy. God can make you happy now. Learn from him so when you do end up having a relationship it will be a happy and loving one. Learn to be happy now by trusting God for your joy and peace. When you trust in God for your joy and peace you experience a happiness greater than anything you can imagine.
Don't block your happiness and peace with negativity and doubt. Block your negativity and doubt with the joy and peace you get from God when you place your husband fears and all fears in God's hands.
"Cast all your anxiety on him because he cares for you" (1 Peter 5:7).
Delighting is being happy. Aren't you thankful that God loves you and watches over you and you can cast your cares on him. God wants what is best for you. He doesn't want you harmed but wants you joyful and having great peace. To have the joy and peace you need to trust him for it and block all negative thoughts that says you can't have it.
Be blessed.
