To Tell or Not to Tell

I wonder if other widows/widowers struggle like i do to let people know that my husband died. People in my office know because i had been with that job only 4 months when it happened. However people that have started working there after his passing don't know. I wonder if I should tell them to save them the embarassment and me the awkwardness of them assuming that i have a husband since they know I have kids.
It's just awkward for me if someone makes a general comment about spouses or husbands and I sit there quietly and not say anything.

Entertaining

So tomorrow I am having 2 familes over for dinner at my house. There will be a total of 12 of us. This will be the first time I have entertained at home without my hubby alive. I have made it simple so I am not really cooking. Just throwing a premade lasagna in the oven and baking some chicken drumsticks. The point of the get together it to see out of town guests and let the kids play together. As much as I want to do this and do feel that I am finally ready, part of me is struggling with the idea of entertaining on my own. I miss planning out the menu with G, I miss him helping prep the food, cleaning up the pots and dishes while I am cooking so that "there is less mess to clean up later", helping set the table,setting out the drinks and glasses, lining baking dishes with foil for me, doing dishes after dinner so I can socialize with the guests. I miss it all. I know once the guests arrive, all will be fine but just thinking about it is the hard part.
