Was married for 13 years, now been divorced for 18 years. Life does get better - quickly.
She blindsided me, but being the nice guy that I was I thought giving her some time / space might help. It did help.....her pocketbook. I was having a good financial year that she ended up getting a good chunk of because of my delay in filing....so.....it's hard, but my advice is get this marriage over with ASAP. Cut your financial losses and move on with life ASAP. Being a nice guy and trying to work it out cost me an extra $100,000.
I still stayed very good friends with her parents and many / most mutual friends. (Great revenge, a nice side benefit, really pissed her off!) She later got married again, that one lasted seven years for her. Her then husband called me one afternoon, said he was divorce victim #2. We kidded that she worked for NASA - thought the world revolved around her.
Since you can work at home.....get a good pet like a basset hound. Always happy to see you, won't cost as much and (seriously) is a chick-magnet in public!
I'm not serious here too often, but I will be right now: it's heartbreaking, it won't be easy, you'll be miserable at times, but life will be better. The sooner you fight through this, the sooner you'll bounce back!
