Treese, forgive me but I can't remember IF your children know about their "step" brother-is that the right word? but either way I do think this should be talked about before hand rather than an accidently meeting. Surely H wouldn't just sort of bump into them and say to your son oh by the way this is my other son! NO I can't even think he would do that.
Don't torture yourself with wild guess's talk to him about the possibility.
Calmly I suggest writing it down and practise saying it first-helps to keep the emotion out of it. Have a few ideas of what your reaction will be IF he says yes and then you can voice your disapproval/displeasure. Also have another option IF he says this will not happen. I am also sure the boy's mother would not want this to hapen,she will be anxious to protect her son as well. Deep breaths and write down what you want to say--can this be face to face or over the phone chat or email?. Hope that helps. You can do this Treese and you will get through this. Women are so much stronger than we think. Take care.
