Agree with this, and YANBU @ValerieVomit
Someone else who springs to mind here, although they did seem to have a genuine love, is Celine Dion and her (now deceased) husband Rene. They met when she was 12 and he was 38.
He re-mortgaged his house to fund and promote her first album. He was very close to her, and was her manager, (from when she was 12.) They became an 'official' couple, and declared their love for one another, when she was 19 and he was 45.
I mean she was an adult then, but it's still a bit 😱
Any grown adult - especially 35+ who is dating someone young enough to be their child, (and who they have known since they were school age,) gives me the creeps a bit to be honest.
