OUCH!!...but as bad as it made you feel, I didn't really get that. Seemed to me to be a farewell of sorts. And there's no indication SHE loves him...OTOH,
Of course your w is tempted to be in another world or life. Her SS is a handful and he's not going to get easier as he gets older and stronger and more hormonal. OMG I would dread that and I would be tempted to jump ship too. At some level she knows it's not you though, and btw, where is HIS dad?
It's almost hilarious that she thinks OM is 'great with ss"...really? Based on one evening?? Well good luck with that. (Hopefully they'll all go on a camping trip and if OM is still "great" with SS, pay him to babysit...)
As you get back to your "Denver focussed" plan, you will feel better and she'll see that your changes are real and lasting. This is just a backslide. So, how does the new improved Denver recover from those backslides, today?
