I like what you were saying here. Here are just some thoughts:

"How many times can one love?
How deep can love lost hurt?
How often can forgiveness come?
How soon can the pain Revert?"

First off, it doesn't really grab the reader's attention with every line starting with how. Try to find other words to place in so it is not so boring line after line. If you can't find other words, maybe try to rearrange each stanza so you can fit different words in. But, I do like what is after each how. Just try to use other words, and not the same ones. Keep writing!
