I would only add one thought here that comes from my own experience. I am very sad that I have never had children. My own childhood was so unpleasant that it took me decades to realize that not all children grow up in misery and that it might be possible for me to create a loving environment for children of my own. And when I did realize it and also realize that I wanted a family, it was too late. This was nothing I ever expected to happen, but there it is as reality today.
So no, I don't think there is any inherent reason why you should not leave this issue on hold except that in general, while I left the business of pursuing my recovery work on hold, life was passing by and with it I let some options close themselves off that I wish I had not. Obviously we all walk our own paths. But I'd just suggest that if you're leaving it on hold for a reason, that's great. If you're leaving it on hold because it's painful or difficult to face, it may get tougher and produce unexpected problems the more you wait. Personally, I wish I had gotten on top of all of this stuff back when I was a much younger man.
I don't mean that to sound preachy, because obviously I don't know your story. So if it sounds like bad advice to you, it probably is and in that case please disregard it.
