(2) Upon a finding that a marital communication is privileged, it shall be inadmissible if either spouse objects. Such communication privileges shall not apply to proceedings concerning abuse of one (1) of the spouses or abuse of a minor in the custody of or under the dominion and control of either spouse, including, but not limited to proceedings arising under title 37, chapter 1, parts 1 and 4; title 37, chapter 2, part 4; and title 71, chapter 6, part 1.
