do nothing...
just have some self respect... if u haven't that yet. If her IL is decreasing, you aren't able to do ANYTHING to increase it... Don't believe in "Be busy..or similar ****", you'll just make worse.
I guess you probably've done something, that made her IL to decrease (yes, that may be "too clingy" "too much interest"... in concrete - no common sense, of what's too far.).
Whole year I've studied DJ system, went through all possible "stages of mindset", and I see now how misleading is all this... I suggest you reading SW101, than DJ bible. if you don't have short attention span. Of course it's your choise, but you'd save time (even, A LOT of time).
BTW. who'll try to start a flame on this, don't bother. whole year I was struggling with DJ system, it has seemed like some miracles, just... I didn't get any ***** (as more than half "theoreticians", who sits here..). Then I found SW101, and "wuala", results appeared afer ONE (just one f*ckin' week, of a little patience reading D's stuff in her writing style..) week.
and results were ****in' awesome..
