So, I might try a new 180. I'm thinking that I will continue to not call her (its going to be tough!) and ONLY allow her to talk about herself.
Might I suggest that you stay in contact in ways that do not necessarily include a conversation? Texting or emailing a funny video or joke is something that can make them feel you are thinking about them, but doesn't require getting into a big conversation. I know my 26 year old appreciates when I do that.
