But I am also going to restate that you should always agree with her. Also, Listen to her with no distractions - turn off the TV, Radio, anything else and look at her an REALLY LISTEN.
Also be happy, upbeat, Friendly, etc around her - make any contact with a plesant time for her. If each time she contacts you she feels good and your happiness rubs off on her, and when that contact ends she feels better than when it started, then there will be no deturrent in contacting you the next time and she may even look forward to the next contact.
I see some positives and alot to build on, but it will be a hard road. But then, if it was really easy then it would not mean as much. The truly great things in life are worth the effort to get them.
