It does come down to the two of you & how committed each one is to the other, what are both of you willing to do to keep this situation from becoming a cancer. If it does bother you that much, you must take steps forward if you want change, otherwise I can't see from my perspective (DAM Dumb Ass Male), that it will change. I re-read your original posting and it was like that from the very beginning & it's unlikely that it was something you did or there was some kind of environmental change. I kinda hate to ask the obvious but is he gay? I mean all the outward signs point in that direction and I don't want to seem spiteful but assuming you are sexually attractive, it's a little hard to fathom. I think you really need to sit and have a long, long, long talk because this just doesn't add up (and I'm a geek as well). It doesn't appear to be you as the problem but then again, we're only hearing from one side of the picture. It is entirely possible that you appear to be either too "motherly" (if there is such a term) or somehow you intimidate him. Whatever the reason, you need to find out quickly, otherwise you'll be stuck in this morass of ambiguity and questioning yourself. Not good for you or him or your relationship.
