I'm torn on whether this is a FYL or a YDI due to lack of information. I hate hearing of women using sex to get what they want. (Yes, I know that a lot do, but it makes me somewhat ashamed of my gender.) That being said, if she has asked you to help out and you have repeatedly ignored her requests or made promises just to not follow through....YDI. If she has tried and nothing has worked she probably feels this is the only way to get through to you. If she has just hinted around instead of asking outright and has jumped right into this method, then FYL.

Wait her out?

Sounds like you need to make a chart for things she wants you to do. Mow yard - xyz favors fix plumbing problem - abc Per hour with inlaws - 123 you get the idea..... She needs to realize ways she takes you for granted

Ditch the bitch and find yourself a nice boyfriend.

seriously if my wife did that I would be filing divorce papers, never know what she is doing when you aren't home

Divorce the bitch on principle for controlling your ass. Then punch yourself in the balls for even thinking to follow such a ludicrous suggestion.

That's ****** up

Not sure if I like this or hate it... There's a war going on in my head on what side to take on this.

You sir, need a divorce. She's clearly not interested in you as a person.

Chances are- and I could be wrong here- you probably weren't doing your share of the housework. Or maybe you are doing your share, but it isn't noticeable. Or your wife is crazy...
