Blackie, How do you normally handle these moods of hers? Could you try something totally different?
For instance, if it is normal for you to lay low until she's better, how about trying something new? Maybe we could all help you come up with some ideas, if you tell us how you would typically react.
Clearly what you are currently doing is not working so let's get going with something else!
I read with interest her belief that you don't love her anymore. I can tell you with 100% certainty that she is referring to sex. If my husband and I have gone a while without sex, I start to have these feelings that he doesn't love me anymore. I cannot see how he can be around me and profess to love me and not take it further. That just doesn't jive in my brain.
It is a simple love language thing, BR. Her love language must be physical affection, specifically sex. So she can't feel your love in any other way--they are nice things that you do for her, and she probably appreciates them, but they don't make her feel LOVED.
Hope today is better for you! Write soon and we will figure something out for ya.
