From my perspective of ignorance regarding specifics, it may be a good idea to be as open as possible. "Burden" him by talking about your worries and insecurities; it is after all a natural playground for an IEI. Make him involved in you and your thought process. If you intend to look for things that you seek in a partner elsewhere, then that sounds... like an impending hardship on the horizon. If you for example need a hug, just say "I need a hug". I cannot tell if that issue is solved or not, so just a thought.
"/.../ anticipate what will inevitable come." sounds so .
I'm in mirage IEI-ILE too (not long this far but seems very promising), so your viewpoints are of much interest to me.
