Lee, I hear your frustration. I know how you are feeling. I am there with you. My PMA has been nonexistant lately... and I don't feel like doing this anymore. Of course, if I look at the alternative, I don't want to file for D either.
On the one hand you are frustrated, but on the other hand you say you do want to do this. Is there any way to go to C together? Is there anyway to talk to her about this? Can you talk to her in terms of how she was feeling so distant from you before, and now you feel distant from her? And that you don't want to feel that way? Would this work with her or drive her away? What are her intimacy issues? Is is a power thing? Try to be brave and talk to her in a nonconfrontational way. Is there another time of day that she likes intimacy better? I know you said the morning was good. Maybe she just doesn't understand how important this is to you, maybe she does and kind of holds it over you. I don't know. I do know you need to work with her on this. Let her know your feelings.
Relax. Appreciate. Be calm. Laugh. Enjoy. Be secure. Be loving. Be loved. Don't personalize. Don't ASSume. Accept. Be grateful.
