You've been dealt a huge blow in the last couple of days and are most likely in shock to some degree. You don't have to figure it all out tonight or even by next week. Get some rest if you can. Then start making lists of everything you can think of that you'll have to deal with if you decide to go the divorce route. Then take that list and break it down into small, little bits so you won't feel overwhelmed. You can do one or two things a day.
And in the meantime, you are not alone. You have a trillion friends right here who can support, help with things you may not think of, listen when you need to vent and bring you laughter when you think you'll never be able to laugh ever again.
We've got your back!
