No offense but I think that's a smokescreen to not work on her own intimacy problems.
Nonetheless the best way to deal with this is to give her more quality time.
Either:
1. You'll remove the excuse.
2. She'll get what she needs to actually want to return love.
My problem with this is that she may be asking for something that is physically impossible. If you have 6 free hours, give her 4 and she demands 8, how can you meet that?
On the other hand she denies you loving physical contact. She provides 0 you ask for 2 and calls you crazy despite the fact she may be able to provide 4.
Regardless, if you give her the time she wants will that help with her feelings of inadequacy, or is this another temporary plug in a massive hole?
