Dear GoingAlone2, may I ask---do you think that he would just be angry--or do you fear that he wold become abusive and punitive, or even violent, if he were to find out?
I think it makes a difference in how you handle this question. If he just gets angry and says stupid things--not a problem! This is to be expected--and he can stay mad until he gets glad!!!! Alanon is for you.
If you fear abuse or punishment or retaliation, in some way--this is a horse of another color. Your situation would need much more support.
If you don't feel comfortable answering this question openly--you can feel free to PM me --(private message).
very sincerely,
dandylion
