I feel that this pisces girl is only attracted to me when I'm in gym and no where else?

well pisces can be very mysterious and keep to themselves to avoid getting hurt also we are know for our mix messages and have a tendency to led people on when we are really not interested so she could actually like u or she is just not interested at all and is just making u think she like u when she don't pisces can be confusing and in some causes don't know what they really what
