Need advice to cope with my bf's fetish and addiction

My bf and I have been together almost 9 months. We met when I was 4 months pregnant and the baby is now 3 months old. At 8.5 months pregnant my bf admitted that he has a pregnancy fetish, it confused me since we really didn't have sex. He had lots of excuses for lack of sex, and only recently do we know that he has a medical condition which makes sex painful, and he needs medical attention for it. Once the baby was born, he became very upset and uptight about any intimacy. That's when I found that he prefers porn and will "feed his fetish". I feel torn because I'm obviously not pregnant anymore and he doesn't seem to be turned on by anything else. We have argued about it because he refuses to even do anything else other than indulge in the fetish. He claims that because it's so unusual he should be able to look at porn for the fetish for hours. It's a porn addiction. He agrees we need to see a therapist, but there's no money for it right now. I just feel like I'm nothing sexually. We cuddle and kiss, but anything sexual, he goes off to do "his own thing". I have stress upon stress right now, and don't understand how someone can make me happy yet miserable sexually and worse is I feel jealous of pregnant women in public and its not just because of him. I have my own issues, because I enjoyed being pregnant. I couldn't get pregnant for a very long time, watched a marriage and engagement go down the tubes because I couldn't get pregnant. Once I was pregnant I loved the feeling, I love my daughter, but pregnancy was easier than a very difficult baby and no sleep. Even with all this I still don't know how to cope with this total fetish. I have offered to get a fake belly and even applied to be a surrogate, since I'm not sure if I can do this newborn thing again. But while sometimes he has said that the fake belly may help, there are darker times when he gets angry and says he doesn't know. I try to understand, I do, but I have needs too. He's a great guy in every other way and he's great with the baby who he has claimed as his own.

At least you both understand that he needs medical attention and therapy. Honestly, the time he's spending on the porn is taking away from his normal life and therefore quite unhealthy. At least here in Wichita, Ks, there are low cost options for being able to see a therapist, a county mental health outreach. Maybe you could check around for something like that in your area?

I was directed to find a sex therapist so that cost is up to me/us. I've approached him about two months ago on a day that was awful. The baby Waac screaming all day and for three hours he was in the bathroom watching porn. When I told him it is an addiction, just like the addict does, he became defensive and angry at me for not understanding.
