Cast an invisibility spell and escape

You have enough time to cast an invisibility spell, and when the priest reaches your position it too late, you are invisible and they can't see you. Silently, you take a side corridor and you reach an opulent chamber, which is decorated like a royal room. A deformed little lord stands before a gold-framed mirror; he's happy and laughs, exposing his malformed teeth.

The nuns and priests around him freeze, their eyes darting between you and him.
The mirror speaks "I told you, oh handsome big lord, your new wife will arrive today, I'm always right, I hope that you buy me a frame with diamonds this time..."
He laughs harder "Ohh my mirror, you are a true friend!"
The mirror speaks again "And you, you are escaping from the priests in the library, my handsome big lord can buy the silence of the people here, but you must marry him, it's your choice"

The deformed little man jumps with joy "Yess please, do you want to be my wife, I want to fuck, and the priest here can marry us now!!"

Disgusted, you have to decide what to do.
If you accept and marry him, he can protect you from the church, but he has very bad intentions with you...
If you refuse, you can just attack them with a silent deadly spell and keep escaping, they are not fighters or wizards...
