THANK GGGGGGGOOOOOOOODDDDDDD YOU DIDN'T GET MARRIED!!!!!
All I can say, is that as much as it sucks (and I rarely use this word) for this to happen, it is so much better than being married to the jerk (man or woman), which will ultimately end in divorce, arguments over the kids, and more heartache. And since it costs more to get divorced than to get married, it's truly a blessing.
You are SO lucky!!
That would be my advice.
