Woman is married
Man is married

Man accepts that woman is married.
Man expects woman to accept that man is married too.
Man is totally honest about his situation. While the woman is full of lies.

1) What would be the reason for the (married) woman to lie to the (married) man that she is on the verge/recently divorced and not living with her husband and in-laws? (claims living alone)

When in fact she has been living with her husband at her in-law's place all the while.

2) Why would the woman want to break up the man's marriage by making him choose between his wife and her.
When she is also married to another man. (Man willing to accept that)
How does it satisfy her that she broke up a marriage while she get to keep hers (if the guy is stupid enough to leave his wife, what follows next is that the woman will dump the guy and move on)

Finally, guy dumps woman (seen through her) and true enough woman moved on to another guy in less than a month.
Does she display any signs of BPD+NPD+HPD
