I also came to the realization that I have ownership this time. That is making a difference.
And you have to show her this through consistent action.
Read the book asap. It only takes a couple of nights. Once you read it, you will see there are 5 different LL's. You have one (maybe two) as does your W. The LL is the way you give and receive love. Unless your LL is the same as your W's, you too have been showing and needing love in two different "languages." You might as well have been speaking Spanish and your W mandarin Chinese.
After you read it, if the opportunity presents itself, talk to your W about it. Let her know you read it and ask her what she thought. If she's open about it, see if she'll take the quiz in it (unless she already has, in which case ask her what her LL is). Would be a good discussion.
