My daughter is ~2 months shy of being 21. Her boyfriend is 46. For reference, I’m 45. She introduced him to my wife and me about half a year ago. Since then I’ve had to bond with him in order to maintain the great relationship I have with my daughter and also keep an eye out for her. But it’s tough, uncomfortable. It is what it is. As we say here “să fie ea sănătoasă” - as long as she’s healthy (health is the most important thing).
I’m extremely close with her. Have always been. She has the same kind of relationship with her mom as well. She feels comfortable enough to talk openly with us about absolutely anything. I asked her the same question myself. She says she never thought about the age, they just “vibed”. To be honest, from their interactions he doesn’t have a “father figure” thing going on at all. He’s kind of childish for his age. I personally feel like I’m interacting with a younger brother when we’re together, not a man 1 year older than me.
That sounds like probably the best case scenario within the circumstances.
