I need to properly update with stag info etc.

But for now...

"Fuck you. It's not your place to say who plays what role in our wedding. Every time you have me thinking that you might have genuinely become a nice person, you prove instead that you are instead a petty, paranoid, self-obsessed arsehole.

So I say again...
Fuck.
You.

You're not welcome - You're tolerated."
