It all depends on your W's reaction when you asked her to read the SSM book. I tried to get my H to read SSM but he refused. Then like you I tried to give him the LL book to read because I thought that the title was less 'threatening' and he got even more annoyed. We've had several fights about the book, I don't think he will ever touch it now but since he's begun to be more affectionate fulfilling my LL a little, I decided that its not necessary for him to read it anymore, although it would be nice, its a good book and I really hoped to be able to share and discuss it with him. Seems silly to fight over a book so its pointless for me to bring it up again.
If your W's reaction over the SSM book was negative then I'll say give it to her some other time or you might just ruined VD for the both of you but stick to your other plans, they're lovely. My H does not believe in celebrating VD. so no such plans for me.
