Hey Mackattack thank you for your reply, it gives me some ammo. And I think replying now can help give valuable information to future repliers.
To answer your first question
if I have alrdy told her that I love her: Yes I have. I have told her that I will always remember her.
To comment on your second remark
showing chinks in my armor/ showing emotions more: I have been doing it more and more. Read below that I actually kissed her in public as much and as good as I could, because that is one thing she thinks I should do more.
And to expand on that. Yesterday we met twice to talk about it. Once for 3 hours. in romantic settings at a lake with nice weather. And the second time also in romantic settings with fireworks. But she was acting all arrogant as if I had to win her over again. Saying "I am not your girlfriend anymore" (whilst sitting on my lap and having kissed me
in front of a lot of people, showing her I'm not afraid to be emotional). So it is clear she still likes me I guess.
Shortly after that she started talking about this guy again. She said she really thinks she should see him. And would ONLY kissing him be ok?
I told her no way. (note my change of what she shud do with him, is it ok?) I told her to sever her contact with him once and for all or sever the contact with me once and for all. Before she said that "she could try and cut the contact" if I'd change (which I am and I think I've shown her). But this time she said the above, asif she had forgottten what she said earlier.
Then I said 'lets both go to our own homes and get some rest'. So that she couldn't end the night and have the control. And because I think the meeting was only getting more negative and actually destroying what I had built up.
update: she just phoned me twice again. And emailed me (we have each others passwords, she could read it if I opened it manually, but i read the email via source code

)
Her email read: I wonder if you have told everyone at home not to pick up the phone (which is so). And how do I know if you'll meet up with me at 11am if you dont pick up the phone?
And texted me:
Let me know via my mobile if I should be there at 11 or not, because it seems you dont want to meet up anymore now... X
We didn't agree on seeing each other at 11am. We agreed she'd call me and then I'd let her know what I wanted 2 do. Which at the moment is not seeing her at all .
I'm going to phone her and tell her:
"That I liked her, and that the way things are going is too paintfull for me (showing her emotion) And that I need space. Also that I will not be joining her, and that she should try to enjoy the day. Because I will be going out with friends later on (which is true)" Note with no saying i love you at the end.
