I think that a lot of SLIs may feel that they are stalked by someone as this seems to be areoccurring theme with a coupl of them that i've known in various age categories. If so, i can only postulate that it has something to do with the fact that their Ne works in the background of their psyche suggesting that there is an Fi manifestation around the corner....hell if i know though.
I've been in 2 SLI relationships both lasting about a month, one lots of contact and the second rather long distance. The first one there was a real almost spiritual connection there and things were going great except i was the idiot at that point in time trying to keep this psychological distance at the beginning and i ruined it. In the 2nd, there were some hidden motives i think and character flaws which indicated that non-personality type wise this probably wasn't goin to work out.
I think that activity relationships are far easier to start than dual relationships (but not better in the long run).
