Fool007,
I may be wrong here, but all the time you are wasting by whining about your problems is not getting you anywhere. Have you ever heard of the term "Sh..t or get off the pot"? Stop whining and bellyaching about your situation and do something about it. No one, I repeat no one can do anything for you. You have to do it yourself. Stop worrying about that woman and start worrying about yourself. I was in the same sort of situation as you...he nor I were married to other people but I felt sorry for him and was afraid to leave but I knew that if I didn't leave I would have self-destructed. You are not too old...my doctor just got married for the first time and she is in her late 50's. Some people don't find love until they are much older. Don't give up...there is someone out there for you but you have to move on and start taking care of YOURSELF!!! So get moving...You can do it. Good Luck!!!
