Snake and Dog, match?

My boyfriend is a Snake and I am Dog. Recently we've been fighting a lot, but I love him and want to try to make it work? Most days it seems like he still loves me but he often gets angry and says we should end it completely. What can I do to smooth things over with him, or to help him in being happy together again, or to support him better? What is the best way to be a good partner to a snake? Thank you.
