So I have a primary partner who lives overseas. I have a "secondary" that lives in my town and I generally see him once or twice a month. I spent some time with my secondary without clearing it with my primary last night because some plans changed while the primary was asleep. Things got sexual and now my primary feels I've cheated on him. I find it hard to agree with that because the secondary has an established place in my life. Is that how this works? I'm not trying to negate my primary's feelings, I'm just legitimately confused.
