She won't go back because she will be busy doing all the things that he held her back from. She will probably land a better job at a better company because he will start making work awkward. After some time there she will realize her real worth and then the real money will start coming in after she applies for a promotion or two. Probably meet a nice guy on some out of town business trip that, ironically, doesn't live far away. 

He'll be like five years older and divorced. His wife cheated on him but that was ten years ago and he's not bitter because he took the time to work on himself. She learns that not all men are like her first husband. This one actually supports her in ways she hadn't even thought of. They work together as a team. They will fall in love, get married, and the whopping double incomes that these two have now make life a whole lot better. Like David Lee Roth said, "money doesn't buy happiness but you can buy a big boat and sail right up next to it."

Thanksgiving with the family that seems to get bigger every year, summer at the lake house and a cruise once a year. One spring the Florida room finally gets put on the house and it barely touches their savings. 

Time goes on and the couple end up with two grandchildren. She has a health scare but comes out ok in the long run. He never left her side. He passes away one Sunday morning from a massive heart attack. More people turn out for the funeral than expected. She still has a few more years with her family around. One winter night the family gathers around her bed one last time she smiles at them all one by one as she looks around her bed. Her oldest grandchild, through bleary eyes, touches her hand and she drifts off with a countenance of contentment.
