Hi. You said SO input was welcome, so I hope you don't mind.
My spouse is currently questioning, and for me just knowing that he has the question has been terrifying. I've had multiple emotional breakdowns where I cry and beg him to figure it out already because the ambiguity feels like too much to handle; other days, I am calm and remember that he is still here, he will always be the same personality and person, that the wrapping paper is less important than the gift inside. But overall, I'm just as confused as he is. I've done a lot of research and education on what it must be like for him, but I can't truly know beyond anecdotal evidence. I don't think your wife is trying to be any more selfish than you are; she is in denial that this is happening right now and nothing she wants to do will stop it from happening. Everyone goes into a marriage with some sort of "plan" for the future, and to one day find out or be told that that happy little imaginary path is not the one that you are going to take is, in short, terrifying. Myself and a lot of the other SOs that I have met online and in support groups struggle with the ambiguity of the situation, and the idea that "I don't REALLY know you." It's uncomfortable, and it does not mean that your feelings or experiences are invalidated. But, sometimes it feels like as an SO who is in love with someone who isn't really in love with himself, we are supposed to stand strong and stoic and just...wait. It's really, really, really hard to wait. It seems like you wife is struggling to make sense out of what seems like chaos, and by making plans about remodeling or having a baby, it gives her a sense of order and concrete future. It's not going to be easy for her, because it isn't easy for anyone on either side, and it still isn't even close to being easy for me, but she is going to have pull up a chair in ambiguity land. I applaud her that she is at a place that she's not freaking out about your dressing, because even that little change of clothes can be a complete shockeroo and emotional trigger for a lot of people. Would she consider going to a counselor to talk about her emotions and her fears? It really helps find balance and footing.
