Marriage book?

[cleoismycat]

Can anyone recommend a good practical relationship/marriage survival guide preferably written in the uk? Non religious based?
Thanks

I don't mean to sound horrible but why a book? Surely the basics should come naturally: love, trust, compassion etc. I don't really like the thought of a 'survival' guide for a relationship. It should be enjoyed not 'survived'

Anyway I hope you find what you need, and hope things work out.
