Maddison,
Please, seek a counselor. If you don't have insurance you can go through your local mental health center on a sliding fee scale. You may not believe it now, but this woman is Irrelevant and even though your anger towards her is valid he is his own problem. She will get her turn so let her go. The problem is within him and she just happened to be willing to participate in his illness.
Women participating in these behaviors are in their own denial and illness, but rest assured the pain and anger will pass and they will be left to rationalize and justify their behaviors with only the ignorant willing to buy into it. Let her go she's an irrelevant element not worth your time. Work on healing yourself and your children. Counseling will work immediately so hurry up get an appointment. Take Care and Good Luck!
