I would ask her what her thoughts were about the videos. If she responds in a positive manner, then (without getting too wordy) you could say something how you would consider seeing some more sent your way. However, I suggest you let her lead in the conversation. At times such as this, LBH'S start talking too much, and the WW will pull away. If she seems closed mouthed, then don't volunteer any of your view points, or get pushy by trying too hard to encourage her to choose a MR help program, or whatever. Just be calm, cool. & collected. She felt you out before she sent them........so wait and see how well she acts throughout the day and night. If you show any excitement over her sending the videos......or hint that it means she's back on board...... she will go cold. So, easy-does-it. Remember the squirrel.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
