I am sorry to learn of your situation...unfortunately there are thousands of others in similar ones.
I would encourage you to continue with the counseling.. perhaps even bring your husband once you have your own emotions a bit more under control... communicating with anger, resentment etc.. makes people withdraw more especially when it is their normal mo.
As you learn more tools through the counseling, I am hoping that your communications with your husband will improve and perhaps he will be able to talk about it.. and even make wiser decisions.. I am sure there are other options.. guilt.. keeping her at his home is only one way..
please keep us posted.. we're behind you 100%
