Can a believer fail AT repentance?

[foodiepeep]

I know that my (deliberate and long pre-mediated) unbiblical divorce (that was strictly for neglect and psychological abuse) was most definitely an awful sin. Anyone who has read my myriad of other threads understands that upon attempting to halt my divorce and reconcile, my ex-spouse adamantly refused (and has already completely moved on).

My question is, however, is it possible that because I could not turn away from my sinful divorce (by dismissing it), that all of my deep remorse and repentance over it are rendered essentially useless and null in the Lord's eyes?

Many here have quoted John 8:11, but my problem with trying to reassure me with that passage is that she wasn't yet saved, whereas I have been for nine years now. How can I ever be certain that God will accept me into heaven despite my sin if, by divorcing this way, I have "produced bad fruit"?

There is no sin God won't forgive.

1 John 1:8-10
8 If we claim to be without sin, we deceive ourselves and the truth is not in us. 9 If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness. 10 If we claim we have not sinned, we make him out to be a liar and his word is not in us.

You have confessed your sin, therefore, you are forgiven and God accepts you as if you have never sinned. What sin you commit doesn't matter as long you repent and turn toward God.
