On the internet, at least from my limited experience with only one dual, our relationship has been marked with feelings of general apathy and misunderstandings, but also crazy swings in and out of love.
(But also keep in mind that he might be crazy and immature, or I might be crazy, (definitely immature here) or both)

I assume IRL you use your functions better and are much more able to support and help each other with real life problems.
