Yeah you have young kids and at 43 you have lots of time to think about your future. Ride this puppy out and boink her if she wants to keep doing it. Just shows you are not a monster. Only a psycho would boink a monster right? Make the changes you need to make and enjoy the remaining 100% of the time you have with the kids. IHS gets easier once you officially wave the white flag and surrender to the unknown. You won’t feel like this forever and you will be happier in the long run.
