Hi there HerrTrubeit,
I think I have suffered from what you describe. Throughout my life my interests and career choices (and the communities that go with them) have morphed from one into another. Sometimes seamlessly, sometimes more catastrophically. What morphed along with them was my sense of who I am, since I was drawing that from the people and things around me rather than from within.
The last four years I have been turned very inward while going through the process of recovering from infidelity and fixing my shit (although personally I like to think of it as becoming a real girl). The community I had pre-D-day was OM and his community. I also had BS, his family and my family but they were very secondary characters in the cast of players in the EvolvingSoul show. Obviously soon after D-day anyone affair related had to go so my community got a lot smaller and I am only just now beginning to feel okay about expanding it again.
One of the really surprising things that has happened is that as I have begun to view my relationships differently (thinking less about what I'm getting out of them and more about what I'm putting into them) for the first time I have experienced a true deepening of my relationship with a significant other, if you will, and to some extent with my family as well. And that's something I had never thought about before. Deepening. I never knew what I was missing. And what it feels like is not anything anyone could have described to me before it started happening. It just had to be experienced to be understood.
Why I was afraid of that deepening is more detail than I should go into on your thread but I guess I mostly wanted to say that I completely get the craving for the new. If you let that part of you be in charge of all the decision making, though, it can limit the range of your experience as an emotional being.
Your post made me think. So thanks and welcome again from this EvolvingSoul.
