Bob had and has no place in a discussion like yours.
Was your H receptive to your concerns? Any promises made to get his profile off the sex site?
Hugs to you. And good for you for not going ballistic on him. You may not like his choices, but the only way he's going to feel comfortable telling you things (with honesty and full disclosure) is if you make it possible... that is, no yelling or tantrums.
Good progress.
