Hi Abbey - I actually went to an attorney in Nov last year and only recently told H about it. I went to find out my rights and what I should be worried about/prepared for. I just did a free consultation and not to take action.
Go out tonight and put some sugar in his gas tank. That'll bust up his morning ride. mostly kidding
It's totally normal to be emotional with kids going off to college. Plus you have all this craziness going on. Could you be pre-menopausal? (you don't have to answer, just something to thing about - maybe talk to your general doctor.) The hormone changes could be stressing you out even more. Or maybe you do need meds - go see a psych. If you need some help getting through this, take it.
I do think a PI and an atty will help you take some control of the situation - not even to confront or threaten H with - but so you really know what you are dealing with and fighting.
Hope you have an amazing vacation! Send your kids postcards
