My sister’s ex is my mom’s age (25 year age gap). They dated when she was in her late 20s. Honestly they had a great relationship and, while he was a bit “immature” for his age (financially), he was a really awesome dude and they had lots in common. The main reason it didn’t work out was because she wanted kids, and having kids with a man in his early 50s, who aleady had like a 20 year old kid, is difficult.

I think that’s what often causes issues in big age gap relationships, they’re often at different points of family/career development.

The flip side of this is that I met my uncle’s (61) girlfriend, who is, I believe, 25 or 26 and I did get the ick because she’s younger than two of his older children and has braces that make her look a lot younger than that. Most people thought she was a friend of his youngest kids (who are 19). She’s nice though I guess. And my uncle needs therapy, but that’s not necessarily related to this.
