She said it on day of break up and a few days ago when I was trying to re-initiate after RakeHell's advice. Didn't sound like it was ultimatum. More like a statement.
Play by play in days before break up was written by me on page 7.
1) Basically she was away all June, came in July, saw her as normal, did many nice couple activities together packed into a tight schedule as she said she was going to go home again soon.
2) No real signs of drama under surface - except her being caught up in various family matters and me needing to ask her repeatedly to extend her stay here for longer - to quote from her "There is not much for me to do in London now.. I know you are here, but...." - this nonchalant attitude if she stays here to see me for longer or flies to her parents surprised me (and I should have acted here)
3) She asked me if I want to attend her masters degree graduate reunion event about 10 days before break up - which I declined, very foolishly as I wanted to concentrate on work...
4) Day of break up: I met her in evening after she spent the afternoon with her friend that she invited me to meet previously...
