Hello, I am here to help, let me review your issue
In my opinion, start with your daughter
ask her if you should talk to him and let that be her call
these things happen and I am sure you had the wind knocked out of you, twitter is a hard place to navigate. I am sure they will understand. Once cleared with her. Since you are good friends with the mother, if she will not discuss this with her child, it would be best that you have a talk with her.
I do believe that you feel better explaining it to him, but to go to him without asking her first, would seem to be a further intrusion. I know at this age it feels like you are walking through a mine field.
And beyond that it is great that you check her twitter, and any other social networking sites. You just made a mistake. We are human after all! Tough being a mom. What else can I do to help?
absolutely! I didn't want to make things too awkward with their family, considering we parents have a close relationship outside of them. I should mention that he was sexually abused by an adult several years ago (a male, I'm female) and has a hard time trusting adults now. So he is making a bigger deal of this than a typical boyfriend would. Thanks for your answer.
That is very understandable. He most likely is suffering from a little conspiracy theory on his part. I am sure you can settle this all down and it will blow over. Honesty and communication are the best solution to this problem.
This is what I always tell parents with children this age, that come to me. The best you can do is put yourself in their shoes, you are already doing that. Remember, some parents would not give this a second thought, you are going to great links to do the right thing. Pat yourself on the back
and breathe, this will pass.
