I have a lot of personal issues that need to be addressed before I can consider a relationship w/ anyone
I can see why you want to have your love returned - seems like you haven't seen enough reasons to give up, but you don't have any hope for a reconciliation with your W to move forward with.
So can you move ahead and ignore the relationship, not moving toward D at all, and just GAL (work on yourself)? Let her do the D work if she wants it.
Where ever you end off with this relationship, remember that you can learn from your mistakes (and hers) by making you the best you can now.
We've all had these low days...I'm sure you're going to get past it!
