I've had this happen with 4 different girls 3 of em from this gym I'm training at now and 1 from a previous gym. All same behaviours though. Not sure what it means and it's giving me a massive headache.

We all know each other to a certain extend and have had great conversations as well with lots of IOIs on their part as well and I see them very clearly (torso pointed towards you, genuine smiles and laughter and giggles when I'm jokingly pointing out they're ugly in a sarcastic way, maintained eye contact etc etc).

Ussually after 2 - 3 weeks these gals start pretending that they dont see me when its pretty clear that they do and couple of them have an angry facial expression on during the time of pretending to ignore me... So that's pretty confusing considering the fact that everything has gone fairly well and they were the ones that greeted me first most of the time with a smile on their face during the first and second week.

So what always happens is I take the mentality of (well if she looks like she doesnt want me to greet her or let alone talk to her, fine I'll just do my thing and not look at em at all) So what always ends up happening is that after about half an hour of just concentrating on my workout and pretending that they dont exist, I can always see from the corner of my eyes that they keep looking at me for so long that it starts irritating me enough to look at em back and when that happens they say hi and wave... Are they interested or just attention whoring?
