If you can convince her to go to therapy, that would be great. It sounds like you have more of a miscommunication problem than anything else. I almost cried a little bit at how you wrote you felt about her. Make sure she knows it constantly. Every day is not too often. It makes people feel reassured about their love. You don't have to smother to be expressive, there is a balance. Lots of love and hugs to you both.
