Many marital issues can be worked through, and many of them simply can't. If you have two people who want the marriage to work, and two people who are really willing to do the work to heal the marriage, it is possible (although not a guarantee) that you can make this work.
And… it is still true that too much water may have gone under your marital bridge to be able to continue on with the marriage.
But how would you know? And more importantly, when will you know? Because if you're anything like I was when I was at this stage, you've been pondering this for months, and maybe even years.
You're waiting for this to be really fucking clear, and it's still not.
