To give a timeline of what happened in last 2 months:
Late May (shortly before her flight back to Turkey) she suddenly announces that she can't be with me, "you aren't meeting my friends, I can't give you anything except sex, I feel like I am holding you back blah blah blah" - I manage to smooth things within days
3 June: flies to Turkey. We continue daily communication while she's there
1st July: flies back to UK with her parents and brother. Her parents and brother stay with her here till 10 July. She is with them 24/7, I don't get a chance to see her.
11th July: her parents are gone. I finally see her first time since late May
A few days later: she tells me that she (or her father) are booking her a flight ticket again back to Turkey on 28th July for another month. I am surprised (and a bit hurt, internally, I wanted her to spend summer with me). I ask her why so soon. She says "well I have nothing to do here in UK... I know you are here, but...." I tell her, "well, I AM HERE", to which she doesn't really respond clearly. I ask her to try to postpone the flight, she agrees to try.
Next 10 days (till 23 July) we spend a lot of time together. I take her various places, for a day at the beach, museums, all this stuff. I repeatedly ask her multiple times "have you changed your flight? I want to spend more time with you"" To which she is being a bit vague, "I am asking my dad, he hasn't done it yet, looks like the airline does't want to give a refund...Would you pay for my ticket if I change dates? Haha only joking."
It all felt a bit like she doesn't really care if she spends more time with me or not (I frankly told her this). Once again, I felt somewhat hurt and surprised internally that it appeared like I wasn't in her near future proper plans for the summer. Once I frankly said this to her (in a message) , she readily messaged me "postponed my flight till 5 August".
25 July: We spend more time together. She says something like "It will be one year since we met soon...And I've done fuck all in the last year...No job, just useless..." I am already planning some stuff to do for the anniversary, I say nothing because I want it to be a bit of a surprise - my intention is too tell her a little later, but I give her a hint that I am planning to do things and see her on the anniversary (just don't tell her everything).
28 July: I tell her "lets do yoga tonight and tomorrow we make a daytrip to the beach". She hangs out daytime with her friend, meets me that evening. So we do yoga then when relaxing afterwards she comes out suddenly with "I can't do this".... and you know the rest.
So literally, around 4 weeks before the anniversary this happens: she (or her family) book her a flight back before the anniversary, she seems fine with it and doesn't seem concerned about me. Then I repeatedly tell her to change the flight date and that I want to spend more time with her. She eventually does it. All this time she seems to be happy to hang out with me...And then suddenly one week before the anniversary date she breaks up, literally hours after agreeing to go on a daytrip the following day.
