Have NCd
My husband and I separated in March. three weeks after the separation he began seeing another woman, they are still together now. I think it's safe to assume they're shagging.
We had been married less than a year, and I have said I would like a divorce based on his post separation adultery (which I have researched and is possible).
He is refusing as he doesn't want it on record that he committed adultery. I don't really see the big deal, it's not like you have to take the divorce certificate into job interviews or hand it out to prospective romantic partners.
He is apparently concerned that in hundreds of years a distant descendant might go on 'who do you think you are' and his adultery will be outed. 
He also says that I cannot prove that he has had sex with his gf.
Honestly I just want some real closure and a divorce would give me that. I am not currently ready for a new relationship, but when I am I don't want the fact that I am still married to be hanging over my head and if he will not agree to divorce on the grounds of his adultery then I will be forced to wait until March 2015. it doesn't seem fair.
What can I do?
TIA for any advice
