And don't forget - not being compatible with someone can be a very good thing.
On this forum, there are a number of people who are divorcing after years together.
I'm not saying they made a mistake by marrying their partner (how would I know that?), I'm just saying -
There are plenty of people around who 'white knuckle' it with someone when things really aren't good.
And if you didn't do that - if you stood by your values, held your ground, and refused to fight to stay in something which just wasn't good for you... that's a win.

I know it's hard - thinking of you.
But move forward
