Is OTHER wrong in the post ? POST : Throwaway for obvious reasons.

My coworker is currently pregnant and everyone is gushing over her constantly. All I hear all day long is pregnancy jokes, comments, or baby talk. Especially now as her due date is around the corner.

I am happy for her, but I have had 3 miscarriages within the past 13 months. The last one I had major complications with and there is a chance I won't be able to get pregnant again as a result. My coworkers are aware of the last one because it happened later in the pregnancy (22 weeks) and we had announced. 

I'm genuinely happy for her, I really am. And I try to be supportive. But, I cannot make myself be enthusiastic. 

The office manager confronted me about it this morning because I'm the only person not constantly asking the pregnant coworker how she's feeling, etc and the manager noticed. She feels I should be over what happened or at least be able to pretend enthusiasm. Again I have always been supportive and kind to the pregnant coworker, I just don't gush over her or start conversations with her that involve her pregnancy or child. 

I thought I was doing fine, but this confrontation by the office manager makes me wonder if I'm really being an asshole? I don't talk about my miscarriages with any of them anymore, not since I was finally over the medical complications and even that was just because I couldn't do things at work that I normally do without risking a trip to the ER. I'm a very private person and I while I was open with saying "I'm not ok, but I'm doing better than yesterday." I never opened up to anyone in the office about what I was going through beyond just "this happened and as a result I can't do X until my doctor clears me for that type of work". 

I honestly don't know if I can fawn over my pregnant coworker at this point. I feel horrible about it after what my manager said, but its all I can do sometimes to just smile and nod to the conversation regarding her pregnancy/baby instead of crying. I don't expect everyone to treat me special by any means, but am I really the asshole for not pretending to be ecstatic about this?
