HI, I always find that doing something nice for someone make you feel good too. So hopefully you will benefit from these nice gestures you are going to make as much as she will. Think positive and enjoy!
Perhaps if you have been feeling low and are unemotional, that might explain why she isn't very forthcoming. It must be hard for her to deal with you if you are depressed and uncommunicative. She must think a lot of you if she's still with you despite this. I'm glad you're getting counselling for your depression, but I think you should give her credit for sticking with you. Hope it works out for both of you.
