Not that complicated. What kind of open relationship model
are you seeking?
Which is it? For YOU? (Never mind him for a moment.)
Just take the first baby step of sorting yourself out to YOURSELF. What do YOU hope/seek at THIS time and at THIS place?
Because when I was younger I thought I wanted to fly like a poly solo.
Then I ended up closing down to a "V" shape dating two BFs.
Then I broke up with one and then I married one of 'em.
Now as a married, I've been Closed a long time. Only just now thinking with DH about Opening and what the next shape might be.
