For the last three years of our marriage, we have had so many communication problems it started becoming evident that we are two entirely different people. We have a five year old. I talked to my husband about separation/divorce. He says he can see that our miscommunication is a symptom of something deeper, and he most likely is referring to our different personalities. He said this before, but I couldn't believe it, now I do.
I am a social butterfly and he is the classic hermit/recluse, etc. Although our greater values in life are the same, our day to day values are quite drastically the opposite.
Anyways, I am on a break on my own, and I am thinking on what to do. I can imagine separating from "him" but I cannot imagine the new reality that would create for my child. He can still keep the old apartment with her old room, I suppose, and I most likely will move to mom's house, which is 2 minutes away from our current apartment. The living arrangement won't be drastically different for my child. However, sometimes I think that I owe her a sibling from the same father. I know this is crazy, but I am really very emotional about leaving my child in the world without any same-parent siblings.

Sad. Help?
