Dear janemarple:

The significantly troubling aspect of his behavior is his hypocrisy- that he bothered to tell you repeatedly that women should dress conservatively, pretending to be a conservative man, and then being involved with those sites. When you confronted him he pretended it was nothing really, and even after he had time to contemplate what happened, after he moved out, the best he came up with is that he did nothing wrong.

How can you  possibly trust him after that (not a question that I am asking). If he expressed being conflicted on the matter, that would be one thing, but seems like he is comfortable with his hypocrisy. Not likely to change something he is comfortable with.

I think that ending the relationship is the right move on your part, before you discover what other hypocrisy he is comfortable with.
