<human>: Condense the text into a few key points

My wife has lost her desire to have sex. For most of our relationship, we've had a great sex life, often times having it every day or more. Several months ago, things changed; Her business took off, and she ended up working 7 days a week. She's also had a ton of stress from wedding planning. Overall, I think stress has killed things for her. She's now working a lot less, but things haven't really been better. 

Since her sex drive died, we very rarely have sex. She is typically only in the mood when she's ovulating. Otherwise by the time we are both home at night, she's too tired to really be into it. 

I've tried lots of things to put her in the mood. She gets hour long massages from me several times a week, as well as a delicious dinner, and me doing house work when I can. I should mention I work two jobs, and work daily, for about 70 hours a week. 

The lack of sex has been hard on me. It makes me feel depressed, unable to sleep well, and unable to think straight. My wife knows it's rough on me, and sometimes "is willing" to have sex with me but isn't actually into it at all. For me though that isn't enough, I feel she has to want it too. She wants to fix her sex drive as well, and is trying to drink a tea that is meant to help, but to no avail. 

Any idea on what we can do?
