Hey Grog you are doing well. What that bartender said made a lot of sense. I know it sounds trite but counselling can help if you find a good one. Having said that after seven years of marriage to my first wife and fortunately no kids I was done. I bent the ears off of a couple of fellow workers as they acted as my "counselors".
You have come out the other side. If you feel like the rug has been pulled out from under your feet then it has. You are on solid footing now. If in doubt and you meet someone then there is nothing wrong with living separately. You can feel alone living by yourself as you can living with the wrong person.
Keep on trucking!
