From the Jewish perspective you have competing commands here.
The abuse causes an issue of "pikuach nefesh" - life-risk. Almost any commandment can be broken to preserve life made in the image of G-d.
So divorce is allowed (as we seem to agree).
Now since her divorce was based on life risk she's free to remarry. The very bond/vows/whatever bound her to her husband are null by reason of "life risk".
Now she's free, as the
@steve was asking "is she allowed to remain single?"
For this we have to consider the command to "piru u'revu" "be fruitful and become numerous".
If the woman has not had at least 1 boy and 1 girl (11 boys and zero girls doesn't count) then she has not fulfilled the "piru u'revu" commandment and she
must remarry if at all possible.
If she has a kid of each sex then she has options and is not required to remarry.

life and have it more abundantly" -Yeshua
