As others have said, you shouldn't let his jealousy stand in the way of something you enjoy. I was the same way when I first got into snakes. My husband grew tired of me always talking about them and always wanting to spend time with the snakes. Eventually I realized that the snakes were my hobby, not his.
Instead of kicking your guy to the curb or forcing yourself to get rid of something you love, why not take a different road first. Sit down with him and tell him "Honey, I realize I spend a lot of my time with this hobby. I know this isn't something your interested in" And tell him you'll spend more time with him. Don't talk about the snakes as much. In a nutshell, keep your hobby to yourself and find other people to talk about snakes with.
I had to do the same thing. My husband wasn't telling me to get rid of the snakes, but only because he knew I loved them so much. And he didn't want to come between me and something I'm passionate about. That is the difference here. Your guy is saying "Its me or them" If he's not willing to compromise (and if your not willing as well), then yes, kick him to the curb. If he's not willing to stay with you because you want to keep doing something you love, then he's not worth your time.
