Worth your effort
Format: Paperback
Good book & workbook if BOTH people are willing to engage & be open. We felt some of the questions asked could only be answered if you're already living together ~ we couldn't answer or imagine but just do the best you can & move past those. Think & be honest or it's pointless.
