How do I handle this!?

I love my bf, i really do, but the unfortunate part of the relationship is his allergies and my lack of them. I work, breath and love animals of all sorts. Grew up with Noahs Ark (figuratively), raised a few babies (pups, kits, chicks, etc) and was never without an animal that I've wanted or came across. Then he comes in, and I can't have that as much as I used to because he has reactions. Animals are my life, I'm studying to be a vetenarian and keeper, so how am I to deal with this sudden change? He gets mad when I bring it up as if I'm blaming him and I'm not. I just don't know how to handle having my passion change so suddenly. Any advice to give? Is it on me?
