All I can say is document EVERYTHING. Every text, every phone call, every email. If you ever notice an injury or bruise on your boyfriend’s son, take pictures, and write down everything he tells you. If she has Facebook and ever discusses this situation, take screenshots.

I count 138 characters. If he had replaced “w/” with “with”, it would have been 140 exactly. It seems almost intentionally disrespectful to use an abbreviation like that; why the odd informality unless it doesn’t really matter?
