I may not always have the answers for you but I can still see things maybe a bit clearer than you can because you are in the situation. That is true for all of us. It doesn't matter if you have been posting a month or a year, we are all here to give you support.
Maybe something didn't work for someone and they can share that experience with you or maybe something they tried worked really well. The end result is that you get a lot of people trying to find a solution for you.
Look at the pros and cons of where you are at and decide after some time if moving is best. Don't just act off of emotion. I am sorry to say I it has been a long time since H walked out the door and I truly believe if I had been a bit firmer then instead of being in such shock, it would have made a bit of difference. I think it can for you too. hugs.
