My Brand of Revenge...
I just left a sexless marriage. My husband refused me sex for years, and what efforts he did make were just completely lame.
He is nothing if not unprepared, and he loves to procrastinate. When he starts dating again, I'm sure he will be relying on that stash of condoms that have been in his drawer for forever.
As I was packing my things to leave him, I checked the nightstand and saw the stash. I figured that the condoms must be expired by now and I was going to throw them out so that we could avoid the unpleasant circumstance of having him use an expired condom and knock up some random unsuspecting girl. Come to find out, they were still good for a while.
BUT...I threw them out anyway. Every damn one.
He's logical enough to stop if he has NO protection available, so this little surprise should put a nice damper on his sex life for at least one night.
Then he can see what it felt like to be me for 2300 days...
