Okay I am speaking honestly. But being a SAHM mom with just a teenager at home does change things a lot. As far as her saying she is to tired or wore out. I mean come on.
Hmmm Maybe the best thing to do would be to change this routine and shake her up a little. Do share with her that this is something you would consider divorce over. I think it is great she does consider help or counseling so you have that going for you. But if she doesn't initiate that help or change I can see why you are frustrated.
