I swear if I didnt love her

Matt, if I had a daughter and found out she was having sex at any age (for the first time) I would be pissed too, but it would wear off.....maybe.....
I might sound harsh here, but that is his daughter and IMO she is pure as the driven snow and now you "ruined" that. He will always be her dad, so shut the phone off and leave it be for a night or 2. Again, just my opinion
