Females flare. My betta flares a lot at my platies, and here own reflection sometimes. They also flare at males when they are ready to breed.
As stated, it sounds like you have a female betta. The white spot sounds like an eggspot, which is only found on females.
And as for your question, flaring is fine. It is showing he, or she, is healthy.
