I disagree about these books "not" helping you. Sure, you guys are right in saying that it's up to them to come back you. That is 100% correct. But I also believe that knowledge is power and we can learn things all the time, even if that means picking up a book to reaffirm things that we are not always aware of.
If there is any book that you wanna buy, make sure it's the one about keeping relationships strong, you can never learn enough about that!!!
