Growth, change, forgiveness and many other positives that occur all take time. Lots of it. The only choice you have right now is to work toward improving you.
If your focus is on what's lacking, what your not seeing, what you may be missing out on, what you feel you deserve or any other negative aspect of this, then yes. Time will seem like it's killing you.
Have faith that God is working on the both of you and all good things will come to those who wait patiently. I know you are already beginning to notice changes within you. Keep working, and try to look at this as an opportunity of major growth which can only come with time.
