YTA. For crying out loud she's 35 not 60. Yes, fertility decreases each year she gets older but it's perfectly possible for a 35-year-old to get pregnant without too many issues. Even if she couldn't get pregnant there are other avenues to creating a family... IVF, adoption, fostering, surrogacy. Or they could have just decided together that they didn't want kids... regardless of which life path they went down, none of it is particularly relevant because it is effectively none of your business. Asking about it at all was completely inappropriate. Then you go an proclaim him to be a gold digger, her a sugar mama, insult his job, and minimize their relationship. What a peach.
