Continued question. i think my fiance is becoming addicted to porn and materbation?

The sad thing is that I work twice as much as him and I am never too tired to have sex. Well over the past couple months I've been finding porn. And its not like he hides it. The first dozen times I let it go bc I know eveyone ca enjoy pornbut now its become an issue of him watching porn andmasterbatin and still turning me down all the time. And today it finally put me over the edge. This am he woke me up by turning me on and we had incredible sex. Then I went to work all day and when I came home we turned on the ps3 ad went to watch a show and. Right above the show was porn that he dwnloaded to the ps3 and had watched today. I was so hurt that he could never make love 2 me more than once in 24 hrs bc he claimed to only be able to get off once a day. How can he have great sec with me and then mastrbate a few hrs later. He says he gets bored. Well there is plenty of things he can do besides masterbbate n watch porn. I'm starting to think that I'm not good enough for him anymore and that he is bored with me and that he is becoming addicted t porn and masterbating. Also he doesn't watch just standard porn it is always some real freaky things and he's started to brimg it into our sex and althiugh I am open to do anything that pleases him I'm starting to feel that making love to me isn't what he wants anymore. I am very hurt and I need some rea advice and wha I should d. I mean it would be one thing if we had a different sex life and he wasn't constantly turnin me diwn b.c then I would just think he loved sex but we don't and I really don't want to leave him but its starting to break my heart!! Pleasssseeeee help!!!!!
