separation agreement question

Nah, I'm stuck.  I just talked to a lawyer and no matter what I may think to try, all bases have been covered.  See, my problem is that like an idiot I agreed to a separation before catching my breath and taking a step back.  I was crushed by this girl and then, as my name suggests, manipulated like a pro.  My future ex-wife is a saavy business woman and this scumbag she's with is the same way only he's in politics.  I'm stuck for right now but that's OK.  When all this is over and done with, I will have won the last fight.   It would be much easier if I never had to deal with her but I have kids and there's no way of getting around not talking to her.  What's even worse is that when I drop the kids off sometime, she will meet me with a bottle of wine or a home cooked meal.  Just last week when I was sick she dropped off chicken noodle soup for me!  Does this sound like a rational woman?  I am generally not a jerk and having to be a jerk to someone I loved more than anything is even harder for me.  I do my best to chew my tongue off but sometimes I too feel a relapse coming.  For months I couldn't get out of my own way but now I'm getting better.  For her it's about winning or losing but for me it's about being able to just be happy with what I've got.

Was it notarized?  If not then it's not binding.  Who drafted the separation agreement?
