I've read it and it's good. There's another book out there that will help a l ot it's the 5 love languages by Gary Chapman. Everyone has different love languages that need to be met.
1 words of affirmation- telling you thank you, appreciation, quality time- doing stuff together
3. receiving gifts- it doesn't have to be big things, little things count a lot
4. acts of service-laundry, dishes, mowing the yard, cooking, taking care of the kids
5. physical touch- anything goes here, holding hands, sitting close to each other.
You have to figure out what your primary need is because that is what makes YOU feel loved. If she is not meeting your need then you feel slighted. You generally have 1 primary need and a close second or third. Men always need sex, so don't put that in the physical touch category, when it talks about touch it means you love to have hugs, hold hands, love it when she pats you on the back or gives you a smack on the bottom. If you aren't sure look at what you do for her and generally what you feel on how to give love is usually your basic love language.
