I find something very interesting here. It's classis pursuer distance. For a while there you wanted her to back out of your personal life and not have her come to you for hers. You felt you were getting entirely too many texts a day and were holding off on answering them.
Well now she has gone quiet, tried asking about her day, that didn't lead to a big convo and you feel you are drifting farther apart.
Looks like roles have reversed, huh?
Best way to handle this? Stop doing things for reaction. Do things for you. let whatever comes naturally come naturally. Don't worry about her lack of response or over response. Well, you can think about it, because I know you will, we all do, but don't try to alter it.
