My fiancé won't sleep with me but watches porn!

Ugh..so a few months ago I found all this porn on my fiancé's phone. Normally I never go through his phone but I had a feeling something was going on and I found it. Mind you, my fiancé is a very religious man who a few months before I found the porn said to me that we shouldn't have sex anymore because we aren't married and its sinful. So in April was when I found the porn I started shaking and crying. I had been continually trying to be intimate with him but he kept pushing me away. He even claimed he just didn't have a sex drive anymore. Now I know everyone's different with their opinion on their partner looking at porn. The reason this was devastating to find for me was because here I am throwing myself at him, even saying don't worry about me just let me take care of you and he pushed me away. Claiming it's about religion and low sex drive. Then I find the porn. I confronted him and called him out on it. I said "so, you do realize porn and masturbation is like a huge sin in the Christian religion right? Even more so I'd say than sleeping with your partner even out of wedlock?" His response was simply that he falls short, he has flaws and he knows it's bad. He admitted he used to have a problem with porn before he met me and only watches it rarely. It hurt but I let it go and he said he won't watch it anymore but would come to me when wanting to be intimate. Well I told him I wanted to have sex with him yesterday and couldn't wait for us to be together. He said we could. I tried getting things going last night and he flat out turned me down and said "another night I'm tired". It's been 2 months since we had sex (and it's been like pulling teeth the last few times we did it-it was like pity sex). I asked him if he was jerkin it to porn again and he hesitated and said yeah what's wrong with that..seriously man? I started crying silently into my pillow-so he won't have sex with me but he'll jerk off to porn..so now porn is acceptable in his religion but sleeping with his fiancé is not? I don't know how to handle this. So I should just accept that he won't have sex with me anymore for whatever bs reason he decides? I couldn't feel more unattractive and undesirable at this point. This morning he left for work and said love you and his usual peck on the lips..I couldn't even look at him bc I'd start crying. I just said love u and that was it. I'm at a loss, with the only conclusion that he's no longer attracted to me, I'm ugly and not good enough for him anymore. We used to have sex several times a week and it was amazing. How the hell did we get here..any advice on how I should deal?
