when does the infatuation wear off?

Ah, 8 weeks. You are still in the stardust phase.

After noting some of the responses, this will seem fairly analytical. Just about all my relationships occurred when I wasn't looking or expecting. Aside from the obvious compatibility, my experience has been that the initial stardust phase lasts from 9 months to a year and a half or so. You know, you are immersed in clouds with silver linings, that feeling of really looking forward to seeing that person, still getting to know that person. There still is that level of politeness because maybe not all boundaries have been explored. To me, the real patterns of the relationship emerge after about a year or year and a half where some of the more complex issues/boundaries have been stretched and explored. If stardust hasn't fallen like lead at that time, then relationships seem to move on to a different kind of intimate level.
