I called some people I'm seeing partners, but got scolded by a friend because I guess partner means a relationship that's more "serious". My friend suggested calling them lovers.

I'm emotionally involved with all my people and I care about them. I just get an ick from labels and relationship ladders (abusive family).

I'm looking for a word that's unassuming, but clearly says "I'm not single" so I can easily be honest with monogamous people.

Any suggestions? Lover sounds a little too much like cheating.
