PS

There are options such as couples counseling, sex and relationship workshops and weekend getaways, books on how to improve relationships, and many more. I would think that 99% of them are waste of time and money, but perhaps I am wrong, and if you ask around for good referrals, you might get help with this. She would need to show at some minimal motivation to participate, though. To the extent that she herself offered to just co-exist, currently she lacks such minimal motivation.
