Guys, how do you respond to the 'I love you' thing from a plate?

To me it's annoying as hell, as it usually means all I can do is to kick the girl out and hard next. Shame when it happens to a plate I was hoping to fuck for another month or so.

I have a friend who just jokes about it, ' yeah, I love myself too' kind of thing, and keeps banging them, but personally, I can't stand the whining/crying/other drama, which gets worse and worse unless you stop it early enough.

I mean, why do bitches even do that? Obviously they want to lock you down, but this is literally the most pathetic thing ever.
