Welcome Mavrik. Make sure you read through all the material Cadet posted. It is extremely helpful. Maybe you should consider sleeping in a different room. Make sure that you do NOT leave the house if it comes to that. You must detach from her and stop pursuing. Work on doing some 180's. Do you think that the EA has turned into a PA with this guy?
