GW, I know it seems like it's been forever but you're only 6 months post BD and that is a really short time frame. Most of us don't start feeling normal again and in full control of our feelings until at least a year after BD. Don't make any hasty decisions. Just take a deep breath and relax and focus on you and your kids. Let your W do all the ranting and raving she wants, that's outside your sphere of control. Just try to be zen about it and think of her as a distraction that you're not going to let sway you from your path of being awesome.
Eventually if you go down the path of S and D then at some point you will have to face the reality of someone else buying gifts for your kids and going and doing stuff with them and your W. Just keep in mind that YOU are dad to your kids, not OM. W can throw OM at them as much as she wants but they know who dad is. My kids were 10, 16 and 18 when BD went down. At that age it's difficult, but I am very thankful they weren't so young that they might be confused over who dad is or why they have two dads or whatever. I think it's the same for your kids, they are old enough to know who dad is and you will always be dad. So don't worry about OM, he can't dethrone you. Especially if you keep focusing on your relationship with them.
