How has martyrdom been working out for you so far?
It sounds like you're so afraid of what life would be like without your W, you've accepted your role as her doormat.
Did you have a life before you M? You were strong and confident once, and managed to make it on your own. You had friends, hobbies and a life that didn't completely revolve around your W.
THAT's what attracted your W to you in the first place. Being a martyr and a doormat? Not so much.
Look, you're going to do whatever you're going to do, but if your choice is to be her doormat until she finally D's you and M's someone else, there's not much we can do to help you.
Nothing to see here, people. Wipe your feet on BTM on your way out.
