You really do need to back off. I'm sure the affection you are showing is coming across as pressure for her. Give the words of affirmation instead for now. Although you have done good at achieving and maintaining your goals, are there things that you could be doing outside the home. Something to bring conversation and interest into your relationship. I truly believe that spending too much time together is the end all of of most of relation ships. If you've read DR, you know to do less of what doesn't work and more of what does. You need to find what DOES work because you're not getting positive results with what you are currently doing now. Give her time and be light and unpressuring and unpursuing.
