You've met my mother, when it comes to only children (I think you told me that about her) we get the brunt of all the extreme parenting, sorry mate, you'll have to get over it. The guy sounds like an ass, but that is his daughter and in the long run, he was there first.

I'm a herbologist, I'm wounded you think flowers cliche. Send her favorite if you know it or purple hyacinths to say you're sorry. Ask her when you could see her alone if you don't want to see him, but you'll have to deal with him eventually. Can't opt out forever if you're serious about her.
