I think the op is very focused on image and the materialistic, she’s of the ilk where that is key for her, for example “on paper” is a popular phrase on love island, she talks about this woman’s clothes, holidays, nails, “cute” kids, house, how much money she has, social media, and now of course she has a handsome husband too, he also looks good.
it’s just become too much for rhe op, she wants all these things , she wants the handsome husband, the cute kids, the nice clothes, to get her nails done, to live in a lovely home, have nice holidays, have no money problems, and sees it as the goal, and her jealousy has got the better of her as she doesn’t have these things.
so she’s tried to make herself feel better and tried to find a reason to put them down, to scorn them, and sadly this was all she could come up with, that he will soon be old, that the woman will have a problem in thirty years, so she doesn’t feel so bad inside when she compares.
which is not just really sad, the only person who is hurting is the op, and that unhappiness is like a beacon warning others to stay away.
