Husband Watches Porn Alone Instead Of With Me?

So we sort of had this agreement (his terms). After we had a 3 some (he didnt have sex with the girl though, that he'd have no interest in watching porn because he did something "cool" or whatever, unless it was with me for fun for both of us (i like girls) and i agreed thinking wow, awesome. not only will he include me, but he wont go behind my back, which is a big deal to me. i dont like the idea of him getting to watch porn alone, and not me. he doesnt want me to watch it by myself cause he thinks im more into looking at the penis than the girls, so i agree to never watch it alone. so is it selfish of him to watch it alone and not allow me?? or hassle me about it if i do? i never have either, because i respect his wishes, but hearing that he did it the other day really upsets me, and makes me feel insecure and jealous, and these are issues i was trying hard to get over. i feel betrayed, ignored since he didnt involve me, jealous those girls made him *** instead of me being there with him. i dont care if he looks at them as long as im there with him to finish the job, ha. so anyways. he is wrong right? he was being selfish and should have included me, or not have lied when he said he'd never wanna watch porn unless with me. i feel like i opened up and he is abusing it. he didnt know i liekd women until a week ago when we had the 3 some. now i feel like ive messed things up by agreeing to do that and watch porn with him. now he is just abusing this whole thing. i dunno am i crazy or is he wrong for doing this? mostly im upset that he has slacked on my emotions. i told him i might be a little uncomfortable afterwards and he was great the first few days, but then it just slowed down, and i know that was going to happen, i dont wanna be coddled like a baby, but i kinda feel like he has been pressuring me to move faster on this stuff than im ok with, and if he pushes too fast i might back off alot in fear. he doesnt seem to get it. i just want to be in a loving carig understanding relationship, now im worried i made a big mistake by opening up to him and doing what we did.
