Is it normal to have an affair with your sister's husband
So I am having an affair with my brother in law because my sister has always been the better one and for once I feel like a winner.She has always been the better one the favorite and when I am with him I feel loved.She thinks their marriage is perfect but actually he can't stand how controlling and sarcastic she is.he has a lot of other girlfriends beside me.My sister and him have sex twice a year and he has no say in anything in the marriage so he cheats.he won't leave her though because he likes the way she keeps the house and cooks and the social life they have together.
