I guess it's easy to say "Get on with your own life," if you are not in love with your husband. We got married at 37 and 36. We didn't have children. We did everything together, except when we were working or engaged in our own personal hobbies. We had true love and were soulmates.
Maybe I won't be legally responsible for his actions when we are legally divorced, but I will always be emotionally connected to him.
What do you mean by get on with my life? I would love to know what you mean by that.
