Bunny, I hope I don't sound like a broken record here, but I would HIGHLY urge you to put some kind of safeguard in place for tonight (or whenever). At least maybe tell someone what you're planning to do and arrange to call them to check in by a certain time to verify that you're all right.
Seeing your husband's past behavior laid out like this ... with the addition of taking pictures of other women w/o their knowledge or permission ... it all adds up to at the least a person who has very poor boundaries/respect for others. At the most, a predator who is a tragedy looking for a place to happen. Protect yourself.
I'm sure you do have issues of your own too -- don't we all -- but there's a reason that the general response of posters on this (divorce-busting) board has been much more supportive of your separation than they might generally be. Think about it.
