(((FS))). I would feel the same way about the cruise FS. My H and I always talked about taking the kids on a Disney cruise. Not sure either of us will be able to do that anymore. I know it would sting if I got an email telling me he was taking them.
TBH... I think the reason you are still stuck is because the four of you spend so much time together. From what you write, it sounds as if things are not that different than before except you each have your own residence. I know you are trying to keep things as normal as possible for your girls but, at the same time, I think it is holding you back. Your H has not yet felt what it is like to lose you. He can still come and go as he pleases and even though you are DBing, I don’t think he is very worried at all that you are not a solid Plan B for him. He needs to be worried that he is losing you if he is ever going to think about R.
I rarely see my H. Probably in a week, I will see him about 10 minutes total. Recently, I have really cut down on my texts about the kids. Both of these things have REALLY helped me with detaching. Am I 100% there yet? I’d be an idiot if I said yes. But... I think I am at 85% at least and that has only been in the last couple weeks that I have gotten there and I think it is because I’ve gone as NC as possible.
