SB - I thought about this the other day. You said your H is an IT guy and setup your pc at home. I would make sure that he did not install any monitoring software on it that he could have sent to him. You have said how controlling he is in the past. I wouldnt put it past him.
On the other comment about his family and friends wondering "why now?" For one thing, none of their Fing business. You tell them better late then never. Remember they dont know what H3ll he has put you through. Also, if you look at a lot of stories on this site. I would say 80% or more of them happen around a big holiday because the thought of spending time w a person you arent happy with is hard and because of all the pressure the holidays put on a family to be together.
So the bottomline. Stop worrying about what others think and just know that they have no idea of what you have been dealing with.
Live your life for you now. Not the kids or H. YOU.
