TC. I have been following your thread and I know what your going through, Are sits are so much alike that its scary. I too cannot believe that a woman could give up seeing their children, let alone being a part of their lives, But there is many of them like that from what I read.
My xw moves 1000 miles way to be with BF. She still contacts her MIL, who I was quite friendly to until she showed her true colors as far as who shes backing through this whole mess. My gilrs have also seen it and now have nothing to do with her.
One thing I did learn through this who ordeal is I cannot show my anger. It does absolutely NO good. My girls pick up on it and it confuses them. They need me to be strong and together for all of us and thats what they bank on. I know it'll pay off in the end, Heck I'm already seeing signs.
Another thing you MUST do is to LET HER GO! SHe's living in a fantasy world now and there is nothing you can do about it. She IS going to feel it later. When she wakes up from this and realise what she's done. It's going to rip her up inside so much, That the pain your feeling is nothing compared to what she's going to experience. Im starting to see this happen in my XW actions. She thought after she left and established her new life, the girls will see this and leave me to be with her. This tatic has totally BACKFIRED on her and now she's scrambling. But it's too late. The girls have seen through her lies and smokescreen and have nothing to do with her. Told her not to call anymore. Even told Grandma to tell her not to contact them, This, of course Pissed off Grandma to where she told the girls that because MOm is sending 1000 month Child support, she has every right to contact them, They returned with even though shes sending money, She has NO right in treating them the way she has. And they both have no right blaming me for everything. That that excuse is getting old and they need to look inside. This came from a 16 yr old to her Grandma. Quite insitefull for her age, Don't you think?
What Im trying to say is be the best Dad you can be for your kids. They need you right now to be as strong as you can be. If you feel the anger building up. Do what I did, Go out and buy a punching bag. Im on my second because I beat the SH!! out of the first one. It's great therapy and YOU WILL feel better.
Good luck. I keep looking at your posts and wishing you the best.
