Cheater

I have been sleeping with your brother ever since we have been together. We fool around every chance we get. And even had a threesome with him and his boss in the toilets at the pub. I have also cheated on you with M several times and I still cant get him out of my mind.
I am never going to do it again.
Im sorry all of that is what it takes to realise that you are the one I want to spend my life with.
Never again.
