Hi Harrier, the feelings you describe I am still working on, the frustration I read, has been horrible for me too.
It does sound so unfair to finally come to this stage and still be the one to master up all the courage to guide, show patience, ignore own feelings at times. I have said piecing for me has been much much harder than separation. Because at the moment I felt I was "allowed" to have expectations, I had to learn to pace myself again.
My H hasnt told me I love you and we have been piecing for a year. I did tell him a couple of times but now I dont anymore. To me, it went without saying he should have by now, everyday, every hour, to make up for all the hurt he caused. But he cant. He has started texting me I love you and he shows me he does. I lost my father recently and the way he supported me through this period, "has been screaming" I love you, still, it would be nice to hear it...
I just want to urge you, to try and avoid change of moods and having ups and downs due to her behaviour, as a recation to her. Stay focused and do not take things personally. It may sound stupid but IMO, it's the only way to deal with the coming phases between you.
It's a very fine balance between staying detached and starting to connect again. Healing is something that happens verry slowly. For me at least. Take care, Kalni
