When I first started seeing my primary, he was (and still is) pretty seriously involved with someone else. I started out as a secondary, but our relationship blossomed and now my metamour and I are co-primaries, and we get along very well. It can happen. And remember: clear communication is always the best policy. Talk to your partner and your meta about how much time you want to spend with him as well as your feelings about the "ranking" system.
Hope that helps. Good luck!
