Do you think a relationship can last, if a handful of resentments are in place from both sides?

Most relationships are based off of trust and respect and loyalty for each other , but as time goes on some resentments come into play, from both partners’ basically the blaming game, by pointing fingers at each other , basically you did this , and you did that and they say well you did this and you did that , constantly butting heads over who is right or wrong. You both finally agree you both fucked up , but you both still love each other , Do you think a relationship can survive after resentments are set in stone, or is it just a matter of time those resentments will come back to haunt you both? I know no relationship is perfect , we all go through ups and downs, so is it worth trying to make it work or is it better to walk the other way?
