Can you please rephrase your question? You made a promise to God and you want it back?
Since a promise to god(s) is like making a promise into thin air, yes, you can " get out of it, " since you were never in it.
You have a free will to do as you please, and besides, God already knows your heart. Your desires are already known. Therefore, you might as well do what is in your heart to do. So, "yes" and if you find out later that you want to make that same promise again, well....you can. Free Will allows you to do whatever you desire. It also allows you to believe whatever you want. Or disbelieve whatever you want.
We all make God in our own image.
Ergo. You made a promise to yourself.
Therefor, the question should be, can you get out of a promise you made to yourself?
The answer is, sure. But will you ever trust yourself again in the future. Knowing that you broke that promise to yourself in the past?
I think so, most definitely. Though maybe not... Of that I'm certain.
