I second that Dior, super pressie too
PC, be honest now, are you thinking about H in relation to DD and only DD? Or, could the fact you are feeling a little low due to your friends leaving be causing your mind to drift towards H?
The thing to remember, to keep focussed, is that the way he parents may not be your way but, you are not able to force a change of that. You may not like it but, you have to leave him to it otherwise, you are going to end up in conflict with him again.
On the otherhand, if you find he is in your mind because you are wondering how he is and you wouldn't mind talking to him, you could call him as a friend and just ask how he is doing. There's no law against that and, it might just help get things back on track again xx
