I'm a fickle 12 year old girl

I've spent the last few weeks having doubts about my relationship with G. It never seems like I give enough, sometimes I feel like I'm stuck in a love triangle; she sees the martial arts as competition. This isn't counting all the ways I feel guilty, all the ways I think I'm failing at the relationship. How can she feel needed/loved when we spend most of the time apart? It's a fair complaint.

So with all this going on I've found myself, er, infatuated by a couple of girls in the dojo. I haven't flirted; I haven't done anything out of the ordinary (that I know of). Thinking about them makes me a little goo goo ga ga. But I experience the attraction differently for both. For one, the attraction feels intellectual, the ole "Ah, this person could understand me" She has traveled further down the martial path than I have, and has born the sacrifices of that decision.

The other is a neophyte, but impressed me with the alacrity she picked up the basic boxing techniques. She is a music teacher, classical guitar.

Sound like a 12 year old girl yet? If I don't I'd love to hear your definition of a fickle teenager.

After JKD, I asked her about a ring she was wearing. I felt foolish enough having a crush on this girl, so much so the idea of having the puppy dog syndrome over a married woman a bit embarrassing. Simultaneously, I HOPED it was a wedding band, that a cold hard smack of reality would whiplash me of the daze.
She showed me the ring. It had engravings.
"It's a chastity ring"
The cold hard smack of reality by way of a wet towel across my bare ass.
My infatuation was muted, but still there.
