Approach what subject?
What is it, exactly, that you're needing answers on?
If he says he's not cheating, and YOU don't think he's cheating, then why revisit that on a regular basis? I could see it if he was giving you reason to be suspicious but at the same time, you don't want to borrow trouble. I hope I don't sound like I'm minimizing what he did...I'm sure it haunts you to this day.
From reading your posts, the biggest thing I can deduce is that he's recently become a selfish lover. Is that what you're hoping to address? If so, then I would start by not going along with the bj until things return to a more equitable situation. If he wants to ML, then ML but explain that there will not be any more bj's until he's willing to talk about why he's putting the brakes on anything for you.
