This whole "rewriting" history that our S's go through is probably one of the most difficult things for me personally. I have to tell you that at first it freaked me out before I picked up DB and started coming to this site. I'm much calmer now than I was in the beginning. I'll tell you that there were days that I thought my H was crazy. I mean literally certifiable with the "history" that he came up with. Now I kind of laugh about it. It's reminds me from a line from "One Flew Over the Cuckoo's Nest" - "It’s still hard for me to have a clear mind thinking on it. But it’s the truth even if it didn’t happen." I mean my H gets pretty dedicated to his "truth." I've stopped fighting it, but here's the thing, I don't have kids and I don't have to worry about my H rewriting history for them too. I'm sorry that you are having to go through that but I really think that you handled that respectfully and quite well.
When is the next scheduled visit? I think that your children fighting for your marriage is great, but can also be dangerous. I don't want to see you get into a situation where your W accuses you of turning them. She can't see your posts here so she doesn't know what's in your heart. And if your S is anything like mine, they pretty much always assume that our motives are bad. It's a complicated sitch. The other thing I'm wondering is whether the pressure from children could also be driving her away. I wouldn't want to see that either. You and your W are young but she still seems to be acting like she's in MLC. When you are there, you are not thinking clearly at all and you don't have normal emotions. Meaning the needs of her children are not tugging on heart strings the way they normally would and may just be having the opposite effect.
Here's the thing, you're a great dad. And truth be told, I have no children. So, take what I have to say on that with a grain of salt. I just want you to come out in the best light possible in order to get your W back where she belongs.
