When does one quit praying for something?

[teachme]

I know the importance of being persistent in praying for something, but how do you know it's time to quit praying for what you want God to give you?

For example, my girlfriend of 4 years left me and went immediately to another man.  Well, i forgive her, and I pray to God everyday that she may call me again someday to reconcile.  It's been about 6 weeks, and I wonder if it is time to quit praying for her to return to me.

I know a lot of you are saying to just leave her alone and forget about her, but my love is too strong.  

My mind thinks I have no chance with her, but my heart says that I do.

My question is - "When do I know it is time to stop praying that she will come back to me?

In my humble opinion, Maybe stop praying for her to call... and start praying for God to have His will and way in your life concerning this lady!? Maybe also start praying that If she is indeed the rgith lady for you that God will help her to see that, and If indeed she is not the will of God for you. pray that God will help you get over her and help you find the right one for you. I know that might sound to simple or to small a thing to do but i beleive that God answers our every prayer, sometimes its just that we are expecting one answer and we are getting another.. Dont quit praying.,. just maybe change the prayer a little! That my friend is my 2 cents worth!

I agree with this. Persistence in prayer is an essential, but always our prayers should be for God's will and not our own...
