Interesting that Pezzonovante just posted this topic, because I had been thinking about this for quite a while, I think XoX might have posted a similar topic in the past if I remember correctly. However, my viewpoint is that both subtype relations are positive, it's just that they both offer different alternative paths to dualization?

Have you considered the possibility that you might actually be experiencing an activity relation, since your not getting eachother's functions completely fulfilled? Anyways, your description sounds a lot like an ENTJ-ESFP couple I know.
