How do you guys deal with "just give up" comments?

[sweet-1]

So I'v emade a conscious decision to fight for the woman I love. Yes, there's an OM, yes, she filed for divorce after only 1 month of being separated, yes, she's paranoid and bitter. But I know this isn't the woman I married, I have made a choice to try and bust this. I love and miss her and the kids are very messed up by it. She is so out of character. But even if we don't ever get back together, in the here and now it feels right in my heart to do this.

How do you guys deal with the "she's not coming back" or the "I won't be able to be in a room with her" (my mother of all people), or the "she's walked away, give up" people? I've stated that if on the off chance (looking slim, but not ready to give up), that we will need to move away from both our families (at least temporarily), to which my parents blew right up, that I'm selfish to take their only grandchildren away so that she can stab me in the back a second time. yada yada yada.

What a crappy feeling when your "support" structure talks klike that about the woman you still love. Maybe I'm being foolish, but in a case like this isn't it better to err on the positive side? I've seen her at her best and now worst, and I still firmly believe I'm doing what's best for my kids and myself. Actually just typing this made me feel better. I know she's worth the fight, and she never gave up on me in tough times (before this).
