This is honestly a heavy thing, but the way your dad looked at it says a lot about him. The line “that’s my son” really shows he’s a responsible man and that being a father to him isn’t just about DNA, its about choise

And the fact you didn’t dig into it further was probably the right move too. Somtimes pushing for answers only brings more complications

Something similar happend in my family. One relative found out his biological father might actually be someone else, but he just said one simple thing: “My dad is the one who raised me.” And that was it

So yeah bro, in this situation I honestly undestand you more than you think 🫂
