Oh, the gamut of responses to this question! I use a variety of responses, depending on who asks, where I am at the time, how much time there is to get into the story, and whether I'm in a frame of mind to relive my stories.
I wear my wedding band on my right hand and sometimes, someone will ask if it is a wedding ring. Sometimes, I just say, "Yes." When I don't continue, some people realize that I don't want to elaborate.
I've gotten used to calling myself a widow. I've had 5 1/2 years of experience at it, so that word rolls off my tongue fairly easily. Sometimes I just say, "I'm widowed."
The trickier questions come when someone realizes I'm not from where I currently live. The questioning often starts with, "How did you end up in (my town in Western Kansas)?" If the person is someone with whom I want to become more acquainted, I might give them the whole story...which is that I met my second husband on a young widows support site and moved to be with him, but that he also died.
There is no easy answer, really.
In time, I've just become more comfortable telling my story. I hope you can eventually feel comfortable, too, donswife.
Hugs,
Maureen
