It sounds like you are talking about a problem that doesn't exist. There are other ways to have a child besides adoption. Surrogates etc...If you've already had that conversation with him and you are both OK with not having more kids, why would you doubt him.
Being very logical, if he wanted to have more kids as a number 1 priority, he would have likely had more than 1 with the ex and/or picked late 20s/early 30's woman to date. At this point saying he wants a sibling for his son is likely not a driving factor because it may not be the typical sibling experience with what would be the age difference plus split household with the son. As the situation stands, he gets the best of both worlds. He gets to experience fatherhood but he also gets couple time with you NOT focused on kids. You can go out to dinner when you want, go away for a weekend, talk about a life other than the kids aka what life will be like when the kids are out of the nest but while you are still young enough to enjoy it.
Oh as to him leaving the decision to you, I get that. While I don't necessarily want to have another child in my mid-forties I would consider it if my DH and I were split and I met this amazing man that didn't have any kids and really wanted to have one with me. The guy would have to be driving that bus because I for sure wouldn't be trying to talk him into that. It would need to be one of those things that the added responsibility bonded us together rather than put incredible stress on the relationship (see all the DCUM post about division of labor/stress of young kids). To be in that place, he would need to want it 130%, be willing to do the heavy lifting with child care duties, and appreciate the sleepless nights etc for the joy of having a child.
