After heavy communication, how can I go about pulling away to remind them that I have a busy life, and give them that edge of, "Ohh I could lose him at any minute" without them knowing what I'm doing? Say we've talked quite frequently, and now I want to pull away, what are some good examples of text messages/over the phone statements I can make?

How can I do this without her knowing that I'm "playing"?

How can I do this with the most impact? Ie, what to say to dial up attraction, emotional pull, before pulling away?

Examples are definitely appreciated.

try actually having a busy life, doesnt have to be all work but take a course on something, or piano lessons, help a friend painting his house, go to a hospital and read to kids or elders, join a cleanning parks community, maybe u dont like some of these but the point is that girl sees that u actually have a busy life

and if u dont want her to notice, just dont act nervous when u say it, say it like u say everything else, ey u know i cant see u today cuz i have to take my mom go shopping i see ya other day

Yeah, I wouldn't use the mom shoping thing.

I use this most often : " Ok I gotta go to the gym so I have to get ready."
Happens that I actualy do go to the gym so it's true but it also gives her the ideea that you care about your body / health / way you look. That couldnt be bad , could it ?
