I may be unpopular for saying this, but you have to be prepared to accept God's will, whether or not He gives you the wisdom to understand the "why" of it...He certainly has the right to deny us an answer as to "why" because He is God, but if you are called to singleness, God has a specfic purpose and reason for that. I think one problem may be because you do not want children. The simple fact is that most (I'm not saying all) Christian women want children at some point or are not opposed to the idea. However, some do not feel having children is something God wants for them. You can pray and pray for a spouse all you want, but until you really give it up to God and let Him be God, you probably won't find her. It's a cliche, but the truth is that if you keep God first all the other aspects of your life, like finding a spouse, will be added without you having to pour over them in anxiety. Maybe the "no" means you are not ready for the answer yet? It could also mean that you are not going to get an answer--*Edit* God always answers our prayers, I just meant that it may not be in the way we expect or seem like He is answering. Either way, pray that God's will will be done and not your own and He will surely bless you...I know that's true in my own life. God bless.
