It takes me a long time to form an opinion about anybody but right from the start I was suspicious about STBX's "good will". And I don't think I was the only one here thinking along those lines, if I recall correctly. However, as I usually do in life, I tried to reserve judgment. And you were trying to be fair and open, as you say. Well, I generally support that attitude!
But on the other hand, you can't negotiate with someone who is trying to take advantage. Taking advantage by bullying, hiding facts, omitting key numbers, delaying arbitrarily, on and on. And over this long period of time that is what we have been seeing from STBX.
And this is a problem. How do you negotiate with someone who does all these things? You're trying to negotiate from a platform of honesty, which automatically means you two are not on a level playing field.
That's not fair to you, clearly.
This is where SOL enters the picture, to help level the playing field. I can't tell whether that's happening? For example, was there another option, to wait two years and divorce by mutual agreement? I'm not familiar with your system so I don't know if that was on the table from the beginning?
And would that have been substantially less costly? Did your SOL tell you this was an option?
You don't have to answer any of these questions but that's what I find myself wondering. If you're not a fighter by nature but find yourself in a battle, you hire someone to fight for you. Or, if you can just wait things out and skip the fight, you wait things out.
So now, in light of all this, what do you do to keep the further psychic and financial costs to a minimum? I suspect at the very least your expectations of STBX have been substantially lowered from how you felt towards him at the beginning, at a time when unbeknownst to you, he was shining you on about the existence of OW. You're probably looking at him more realistically now and can appreciate you're better off in the long run without him. That's something right there.
