How old is too old dating 24 year old man dating 12 year old

I have this rule: if I could absolutely never bring this person home to my dad, I can’t date them.

My question is, is there such a thing as “too old”?

I assume the reason for this is they can get younger women to respond to them, so why would they go for me when they have a chance with the 45 year-old version of me?

If their first wife was their age, like a college sweetheart or whatever, they probably feel entitled to a newer model, so to speak. It’s frustrating, not to mention depressing and more than a little humiliating.

I think, I hope, it’s safe to assume that most of us find a 35-year gap extreme.
