Annsixty I don't think that your feelings are at all unnatural, given the circumstances of your first GC's birth. None of us can avoid our 'self-preservation' instinct. Given what happened, maybe you've held a bit of 'you' back, just in case something went wrong again. I'm only guessing.
My GC hasn't taken over my life either but I am still elated at how strong my feelings were when I did meet him. Then again, my situation wasn't surrounded by the fraught circumstances which you had. If it was, I'd possibly feel the same as you do.
You obviously love your GC and that is to be treasured in whatever form it comes.
