Sorry to hear about your sitch. You have come to the right place for support. My sitch is similar to yours in that an ex-boyfriend of my W's found her through Facebook and an EA ensued shortly thereafter and is still going on. You will find many similarities in our sitches. If you want, check out my thread under WAS to see the evolution of my sitch and where I am at now. Perhaps you may find it useful.
Hang in there and good luck!
