Best response. I don't know what father Is feeling because it's really hard to predict how you would feel in that kind of situation. How do you know father isn't some pyscho Marine that can twist you into a pretzel? So many variables here I wouldn't want to antagonize someone going through such a big moment in their daughter's life. I imagine it must be frustrating/embarrassing/scary to watch your bb girl grow up and leave with another man. I don't know though most girls i dated didn't have dads.

My wife’s father has been seriously ill with diabetes for longer than the 11 years we’ve been together. He was never a real threat physically (though he’s Italian-American and all his buddies could fuck me up if he called in favors). He would never actually do that though.

My personal situation is that it was forbidden that I sleep in the same bed as my wife while we were dating and he caught me cuddling with her one morning (mind you I had just come up that morning). He said I wasn’t allowed to sleep over anymore (wasn’t the most difficult at the time because my wife was in college and about to go back for the semester). 

I was ready to go in with fighting words over how ridiculous the whole situation was. My biological father’s wife convinced me not to because he and her father had also fought over her and she gave me the same advice: it just makes the partner choosing between parent and partner suffer.

So I chose to take the loss and apologize for my wife’s sake, even though I did nothing wrong and had nothing to apologize for.
