I take my youngest grandson to his pre-school sometimes, he is nearly 5 and he DOES NOT NEED to have me hold his hand. Your AH asked you to accompany him to an AA meeting, you did so, got some benefit from it as an A yourself. If you want to go back to AA, fine for you, but do it for your own needs and benefit, and better at another meeting. Let your AH go to the AA meetings without you, or not go at all, whichever he chooses is not your responsibility....his problem, his to work out.
I decided Alanon with RAW and AH (both kids of A's) was not for me, when after 2 meeting full of bitchy remarks and angry outbursts, a water container and pot plant flew past my head, as World War 3 broke out. Later of course my then ABF turned up at my meeting and stymied my input, to the point of useless, and I left.
