I must say I am no expert, but I wish my H had told me point blank how unloved he felt that I did not initiate ML or when I would say ok, reluctantly. I never realized how rejected he felt, I thought well, we are ML 2-3x/week so everything is fine, even if he had to beg at times. WOW, was I wrong.
Anyway, my suggestion is to read the 5 love languages book. Have a heart to heart with her so you know she fully understands your point of view and you understand her point of view. If you fulfill her love language I bet she will be more receptive to yours. nik
