Dear Sea,
You always have such loving and kind things to say.I am so glad that you are back, although sorry that your circumstances are painful.
I had a thought as I was reading your post. I will share it.Compost what does not fit.
When you described what seemed like 'yearning" for him,it reminded me of how I felt many times.
I was really yearning for my M ,though.. Most relationships for me was a "looking for maternal comfort. I can see that my deep yearnings,as you describe, was not really for that person but for the feeling that I mattered. It was the desire to be hugged, comforted,nurtured, being special to s/one, being protected. being close, etc.
Sometimes in a "sick' relationship,it feels even more like the "lost parent" . It feels like you can finally get their love, after all this time.
To me,it sounds like you are searching for a more "primal" love than just this man. I thought that maybe my perspective would help. Love Ami
