Summary: went out with HB7 for a year, at first we were both serious about one another, but we began to distance when I found out she hangs out with multiple guys and she suspected I was checking multiple girls. However towards the end she still wanted to meet up for her weekly thirsts for cuddles kisses etc I for a short while (2months) I went along. Eventually I asked her to get serious with me, she says no, I have a AFC hissy right there infront of her, we cuddle hug and part ways knowing that we'll prob never see each other again. (she wanted a F-buddy)
I go off to travel in asia for a month, BTW guys AWESOME way to get over a girl! trust me . When I get back iam all spiritual happy and shit so I do what i percieve to be the right thing. i missed her birthday whilst i was gone, she made a decent effort on my birthday with presents and fun activities;-) so i feel the need to give back. I send her some presents in a box wrapped we have a long convo on phone although initially its going okay with thankyou, i liked ure card i like ure present blah blah, for watever reason she doesnt seem to make her usual effort/ basically she cant be arsed with me. I suggest subtly that i could be passing through her city in a week, and she says she wont be there. So figured she aint interested and doesnt want to know.
Anyways its been one year since and she aint called, texted, facebooked, SPAM and neither have I except one quick 'Hi' message on SPAM about 6 months ago, which she blanked.

BUT Im now looking for all the causal relations I can get, so my questions are guys:

1/ should i go for her?

2/ How do i do this? / shes got a guy on the go, If iam right shes looking for the best thing/ she always is! So if I text her or call her do i approach as a friend and ask for a coffee, or drop a naughty text immedietely ?

when we were going out, if we had a fight/argument, I wud text a ''x'' she would reply back with x (indicating kissing) and we'd continue getting more and more naughty so worked as a great way make amends for damage caused. yeah so i was thinking of Watsapping or texting her a 'x' to see if i get i reply, if not i can always say it was a typo!?

Another idea: when were going out, i recommended she read 'life of pi' which she did and loved, so we talked about that quite a bit coz the book is very interesting.
So i was thinking of texting her: Hey did we make a pact between us that, if they ever made a movie about 'life of pi' we would go and watch it at IMAX together?!
i dont think we made that pact, but i was thinking shed be enticed with prospect of a date

ANY feedback welcome guys
