Burned in the end after 27yrs

I put up with my husband verbal abuse for over 27yrs.  I always hoped things would get better but he never changed.  He wasn't a partner or parent.  Couldn't see my side in anything or listen to how I felt.  In the end, after 25yrs he walked out one morning and left.  Never said much to the kids even.  He just easily went on living his life where all he has to do is work but I have to be the one to constantly be the sole  support to our ADD/depressed son.  Very little contact to his children and now he can't understand why they would be upset at him.  He is now fighting me for the house.  If I could do it all over again I never would have stayed that long.  It basically robbed me of many happy years.
