On one side you have your long term P/H . Y ou spent 10+ years together, you are comfortable , maybe even have fun together but the spark had died. He loves you but he forgets to show it, you never go out anymore, the sex is a chore, he return form work and spends all night on tv etc etc.But you know that you have a best friend/good man to grow old together. On the other hand, is a new flame, exciting, makes you feel alive again. You know how it is is a new relationship , it all starts great. But you have no idea how the future will be. People who found themselves in that situation , who did you chose and do you regret it?
