That's "accept" (except means to exclude...such as "I like all candy, except licorice).
His affair 16 years ago is ancient history and if you two stayed together through that, then you accepted it and chose to stay. It shouldn't be part of your current divorce issues. Porn isn't a reason to divorce either, unless he'd rather view porn than be with you.
Divorce if you desire, but nothing in your post gives the reason for you wanting to divorce. He DOES need to accept you've chosen to end the marriage, and I'm sure he also plays a part in the reasons the marriage is ending, but nothing in your post is anything he should have to 'accept' as to why you've chosen to end the marriage. An affair you accepted years ago, and some dirty pictures on his computer, aren't really justification for divorce (so clearly you have other serious reasons, and you're free to share those with him or keep them to yourself).
