The thing here is expectations ought to be maintained at a
realistic level for there're quite a few categories of people who
would not fit into the above category even if they liked you.
For a start, lots of these folks who claim to be busy are genuinely
busy (for all the wrong reasons, you might add) simply because they
haven't got the faintest clue where their priorities lie and do not
appreciate the fact some sacrifices (such as proper time
management) are needed for just about everything in life. That
said, it'd make perfect sense for anyone to stay away from such
people as romantic partners because the last thing anyone would
want is to have a partner whose lives and priorities are so messy
they'd forsake you for work (and vice versa) during family
time.
