Sorry you are here. Unfortunately, this happens a lot, and you are not alone. As to what to do with all those upcoming events. Keep in mind that you are still the same people, you just aren't living together. There is no reason to not have a social life. Neither of you died; you just separated. So, if you want to have people over for a barbecue next weekend, do it without him. Can you call a male friend and ask him to handle to BBQ part while you do all the other food? That would be a good way to show the world that you are not reeling from this, you are getting a life and moving on. And if you don't want to entertain next weekend, then send a un-evite to the people and say that things have changed, and you won't be hosting a BBQ next weekend, sorry.
