@lifeisabuffet..
Does it matter if I land on her shit list if she is giving me the brush off?
If the girl wouldn't notice if I stopped calling then i am wasting my time, she obviously isnt that botherd and not worthy of the time and effort.
Effort in the wrong place is wasted, the OP would have more success putting his efforts into a girl who reciprocates the effort. Anything else is just trying to ice skate up a very steep hill or trying to push his way through a door while loking at the 'pull' sign.
I'm not sure I have ever met anyone with a portfolio of potential candidates that was not a pro-photographer but if she has, then its time to decide if the OP wants to be the competative dueling type or just leave her to her portfolio and get on with his life.
In this situation the OP has nothing to lose except the vague hope this girl may be interested. That hope is based on what the OP would like to happen and how he would like the situation to be: for them to get together etc.
This isnt happening. I agree she could just be a grounded girl who isn't going to put her life on hold for a guy however I have never cancelled or knocked back a date with someone I liked for anything other than something very important.
Only the OP knows how the meetings go and this will be his best way to guess who she feels.
However aerobics, at least its different to washing/colouring your hair/poodle/cat.
Edit: its been a while since you posted any pictures, some of us are getting withdrawl symptons
