Yes your answer helped me think about this more rationally. Thank you! And I've often thought about watching porn with him, but them my fear of him going behind my back again comes in... Because he and I discussed why he kept watching porn and why it was so hard for him to keep his promises to me, and i guess we both agreed that he was sort of addicted? And so i think if i bring it back into our lives, he'll want it more all over again. :/ Though I could be wrong.

Yeah i told him I didn't like him making sexual remarks/jokes.. etc., with any girl because i think it's going to far. And then he acted like I was over-reacting about it... and made it seem like it's dumb that i worry about that, but I guess we'll see... This fall semester we have classes together again, and two of the classes he's taking she will be in as well.. and I'll be in one of them. So I'm tossing around ways to reason with future situations. He knows I really don't care for her, so, I'll still be nice to her face but i think I'll try my best to stay away from her because just looking at her makes me feel inferior.. >.<;
