1st thing. Your ex is your PAST. If you can't let go of your
EX., why even think about this girl in the 1st place..? So LET'S
GET YOUR MIND CLEAR 1ST... YOU WANNA THINK ABOUT YOUR EX OR ABOUT
THIS GIRL? JUST IN CASE YOU HAVEN'T FIGURED OUT YET... THIS GIRL IS
NOT YOUR EX....
2nd thing. There're MANY PEOPLE working HAPPILY TOGETHER... It can
mean something or it can mean nothing.. Think of me working happily
with my colleagues... Does that mean I would need to have anything
to do with every single one of them...? As you were saying this
girl is mature... I think your thoughts have to be more practical
and realistic too...? Not to throw a wet blanket on you... But do
you have other more obvious hints or evidences in which points to
the fact that she might be interested in you other than the fact
that both are you are 'happily working together'...?
Last thing. Even if she leaves the workplace, you can also request
to stay in contact..? You don't have to be desperate but take the
initiative pls....? If she has the slightest interest in you, often
a girl won't reject your offer for that too soon or directly... And
yes, there're sometimes but exceptions to this... Some who are too
shy or too defensive and fast in their response... Even a playing
'hard to get' girl shouldn't be that stupid as to totally cut off
your chance if she's interested herself...
For the sake of those too shy/ too defensive/ fast to respond type
of girls... You might like to try the '2 pins method'... Meaning
you try to ask somewhere soon to keep in contact and for meet
ups... If they reject you too soon in a moment of hurry though they
might really be interested in you, give them an 'oops period'....
Ask her again when the date of her leaving is drawing really quite
near (but must SURE you get your timing right.. Don't face a
scenerio where she takes leave and left the office earlier than ya
expected)..... If there should be any regrets at all for her, now
should be a good time for her to turn around... And pls remember to
make it easy for her to 'step down'... Some girls mind their image
and 'face'.... If she reject you again, you should very well give
up by then... Cause she's probably either totally uninterested in
you or a VERY hard to get type of girl.....
