Once you hit 30 the age gap stops being creepy and becomes a personal life choice. If you were 41 and she was 20, that would be a massive red flag. But she isn’t a young adult anymore, but presumably someone established in who they are and what they want.
If what she wants is you, congrats!
Oh yes, without a doubt. What truly matters is equal power dynamics, I’d just generally speaking saying most 30s have a few relationships under their belt, know who they are and what they want.
But even that can go yuck sooooo quick. Like with a 30 and 80 year old, clearly one side has a fetish or finicals the other has.
