My W said the exact same type of crap and then lo and behold, there's an OM. You're right, you don't just fall out,of,love. You redirect those feelings toward someone else. If there is an OM then you have zero chance while he's in the picture. Any effort toward working on the R is useless. Affair for is powerful and changes people whom you know better than anyone in the world into people you don't even recognize. Affair fog creates liars, cheaters, and parents that would walk out on their own children.
You need to know where you stand so you can make an informed decision about your future. If you don't know if there is an OM or not then find out by any means necessary or walk out now and set yourself free.
