What do you think ladies? Why do I have to push to get a response?

Based on your letter, it sounds like you have good intentions to build on and improve your relationship. However, some of it is a little vague. Exactly what kind of steps are you looking to take here? Maybe she didn't know to respond because she wasn't quite sure what you are asking. But when pressed she said she did want to work on it, so I would take her at her word and move forward. I think it's ok for you to tell her that you were a little disappointed she didn't respond sooner or more emphatically because the issue is important you. Maybe you can suggest some concrete steps to take towards your goal, such as setting aside time to talk, spending more quality time together, and making an appointment with a counselor by a certain date if you don't feel things have significantly improved. Or maybe you should move straight to the counselor option if she is not open to discussing this with you.
