Hi Star, sorry you find yourself here, you'll get a lot of great advice and support here though.
My sitch is very, VERY similar to yours. From me being an artsy girl, to H making more money then all of a sudden announcing he was "unhappy"...etc..etc..etc..
It's great you decided to go to school, that's a big step you've made in a short time.
Are there any other complaints your H had about the marriage that you could do 180's on that will be beneficial for you as an individual first and secondly for the marriage if R was to happen?
Keep your thoughts on positive things!
