Bad Ending

I come from a large fucked up and disjointed family. I am and always have been clean and sober, but my family history is rife with addicts and abusers of all sorts. Due to this, I haven't spoke with a single person in my family for nearly 10 years.

My wife and I met in our mid 20's in her home state, two states over from where I grew up and where my fucked up family resides. All we knew of her family was that her mother ran away at young age to escape them, ended up marrying an older man who takes care of her, always treated my wife as his own daughter, and they have lived happily ever since.

That was until my wife got talked into doing a DNA test with with a friend of hers and found out something truly shocking. The results were a somewhat confusing but she is the sister of my first cousin, which means that her father is my shitbag uncle. After a truly ugly discussion with my mother in law, she revealed that my uncle is her father also.

So where in the foothills of Kentucky does this leave us? Our marriage, technically, isn't even legal in our state. My wife is now scared to have a child with me do to the birth defects inbreeding can cause. The limited sex we have had since we found out has been awkward at best. The relationship is strained and our future together looks bleak.
