Wow...for a minute there I though this was my thread...Sounds just like my W & I, she wants me to file for Adultery too. I assume it's the same for you, she does not have any grounds to file against you?
I'm also in the UK & for all the U.S folks on here, the D laws/grounds in the UK are quite different to that of the U.S. Here are the UK D grounds for those that are intrested...
* Adultery * Unreasonable behaviour ( You would have to name examples & I would say it can look pretty ugly ) * You have been separated for two years or more and both of you agree a divorce (No reason has to be given, just both must agree) * You have been 'deserted' for 2 years (this is very complex and best not used if you have any other ground) * You have been separated for 5 years or more (No reason to be given & the LBS has no say in the matter)
Sorry I can't comment on whether any of the above grounds work in your favour or not. I do know that in my case, where we have no kids & only the house to consider... It makes no difference if she commited adultery, she still gets half the equity from the sale of this house.
If you want my opinion & you are filing...Then file for adultery, if she's willing to accecpt that. Filing for Unreasonable behaviour, as I understand it, you have to name exactly what & the courts consider this as grounds. It has to be something that says you just can't live with your W after the way she has behaved. I suppose an example would be phycical abuse, Dont quote me on that but thats the way I think that goes.
