Wow! I wasn't expecting to get so much feedback so soon! Before I go down the route of explaining my background, I'd just like to clarify a few things. Thank you for pointing out that "coexisting" was probably the wrong term to use, but in the future  I'll explain situations where them being near one another may be important. Secondly, I was never married to my ex. We had a child together, that's it. Other than being the mother of my son, she holds no value to me. So when I say wife, she's my 1st and only wife.

Hey guys. I'm new here and I'm not a Step parent. However, my wife is and she's the main reason I joined this page. She's constantly saying I don't understand how she feels, and she's right. I'm hoping that I can get some insight to what she's going through and how to handle these situations in the kindest yet most fair ways possible. It's hard being a parent to children from different women with two completely different parenting styles. And when my wife and ex can't coexist, that's even harder.
