Test water first...
call her see if wanna go out and catch up. be casual and do not
broch on relationship issues.
During conversation, check her body language - if she's interested,
should be able to sense it. If got bf, stay friends. If no bf, good
for you but don't be too happy yet. If she's not interested in you
anyway, you might as well say 'sayonara' to any of that kind of
possibilities.
