girls taking forever to reply/dont initiate texts

So, I know these two girls, girlA and girlB.

GirlA: I've banged her once, then stopped seing her for over a month, and now we reinitiated contact. We've been on seven dates but SHE NEVER TEXTS ME. She's done it twice out of 15 texts we've exchanged (or so).

GirlB: says she doesnt pay attention to her phone, neither to facebook or any other social media or tecnology. We've exchanged around 8 messages and she takes around 7 hours to reply, each time, or even more!
We've just gone out once.

I try to simplify things and think that both girls have little interest and this is why one never initiates texts, and why the other takes forever to reply, but...

did you ever meet a girl like any of these two that eventhough she behaved this way was actually interested? I wonder.

i've read some stories about guys complaining that their gf's take forever to reply to any message, like more than a few hours each time, and they're in a relationship! wtf?

1) They're not that interested.

2) They're gaming you (and it's working).

As I've said before I don't bother too much with electronic comms with women, only to arrange to meet. It works because every other dork is texting/facebooking/calling her all the time.

Ya bro, now that I have been back out in the field the girls are running as much game as we are. There are girls out there who are straight up doing the same thing horny PUA dudes are doing, the pump and dump (roles reversed) lol. I got to know this one girl who has built up a harem of sugar daddy's, it's pretty interesting how she is able to handle all this, but she does. Reciprocate her responses, and if that means no response, then move on to another and forget her.
