Life has been crazy and I have not had much time to read and post.
After talking with my IC and thinking long and hard about what I wanted, I responded to my H's email mentioned above. I told him that I was also sad and set forth several things that would need to happen in order to revisit our current schedule and boundaries. I was pretty specific so there is no way there could be any confusion. He is either willing or not.
I figured that I had nothing to lose. If he does not respond or is not willing, then the boundaries and schedule are already in place. If he does, then maybe it will be good for all of us and a new step forward. No matter what happens I will know that I tried everything possible. I will have no regrets.
My H confirmed that he received my email and that he needed some time to think about it and talk with his IC. No response yet, but I am actually doing great. We had finished up two weeks with no family time. I am getting used to the routine and it is peaceful.
H has been paying rent on a new place, but I am not sure if he has moved in yet. I am not asking questions and simply focusing on my life. I was able to get the name of a child psychologist, since we will likely need to talk to the kids since they are noticing that we are no longer doing family things together.
Life is sweet. I am happy again. H still takes up a little too much head space, but I am getting there.
