Prayer that she can forgive my shortcomings

I thought I had everything in life and would thank the lord for my blessings. But I took too long with engagement, worried about other things, and now she does not believe I wanted to get married. We get along and love each other, but she is hurt and will not accept my feelings. I pray that she can forgive my shortcomings of the past, and trust her heart and continue with our future together.
