Hi and welcome,
Well, how to respond. What you are feeling is normal. When you feel the need to abuse because of the anger, come here and vent your feelings. Venting to her will not repair you M, but will destroy it even more.
Have you read the links here with regards to his needs and her needs. I suggest when she returns you fill out the questionaire. If she is not willing, fill out hers how you think she would respond.
Counseling, first, if you have insurance, check with your carrier, you may have to stay within the network for them to cover it. Same with anger management.
I hear Dr. Harley is very good. I have not done a phone consult. Can't afford the fees.
I don't know how he will respond to the bisexual issue. Most people, would have a hard time accepting this. You do not see this as a betrayal. For some, this is also a religous violation, and I dont' know how he will take it. If you want to give it a try, before spending your hard earned money, you can ask the person who sets up the appts, how he will feel about this issue.
Who ever you both use for MC, will have to be accepting of this issue, if both of you are.
Feelings of betrayal are felt by both of you. I think I hear you that the OM and the OW are only just friends to each of you, but how will your W feel about you maintaining contact as "just" friends with OW? My guess is she will not be very accepting of it. Are you willing to terminate contact with this person to save your M. It may be necessary. Will your W be willing to terminate all contact with OM if necessary to save you M. You both will need to have some radical honesty with each other on how you feel about contact with these two individuals. My thoughts are if you both are serious about your M, you both will do what is necessary to save the M, which includes terminating some friendships.
Keep you anger under control with her. A year of daily verbal abuse is alot for anyone to bear. One more may be all she can take to send her running.
Take care.
