I disagree with calling yourself and the kids casualties of this sitch. It's not the end of the world. Hurts, sucks, bites.. yes, yes, yes! But you can/will overcome this and come out stronger. I believe your kids can as well. It's up to you. Focus on what you can do...
Show the GAL how you care for your children, positive chances for yourself and the kids... but show, don't tell.
Casualties doesn't mean 'killed'...it also includes 'wounded', and that was what I meant. I know we'll all go on. I regret that it came to this though.
I have to 'talk' to the GAL quite a bit. She's gonna come to the house too when the kids are there. There is a lot of 'talking' involved, but I know what you mean.
