If anything..this thread is really an eye opener to the practices of the WS.
It basically shows that unless the WS goes thru some major shift and admits to her faults and begs for forgiveness and applies all the necessary measures to compensate for her As and to make sure no other As ever take place...well, unless all of this happens the BS spouse is a 1,000 times better without WS.
It is really very obvious, I am sure, when a WS is ready to fully commit to the M.
Till then, fear that they will betray again is just the natural reaction to an unsure or unrepentant WS....
