One of the first things we learn on here is to never answer or do anything until we have let 24/48hrs go past, honestly its hard but its a life saver..
Yes youre angry and mad at him at the moment that combined with the fact its your friend he is potentially having an A with! First of all why are you mad, probably because you love him still and its hurt talking.. Give yourself some time, come on here and let it all out and folks can give you ideas on what to do once you have decided what you want. As for separation you dont have to do anything yet.. H may push but you have the upper hand regardless of what it feels like. Spend today making sure the kids are feeling secure it will have shattered their world too and they need mum to be strong and show them direction. Dont run your H down infront of the kids just keep reminding them its about you and dad not them and dad..
Thinking of you!
