that meanss that she loves you but she is so angry with you because you hurt her so much - obviously
as for how to get her back: i have no idea.
The problem is that on the one side you flirted with another lady - which really is no big deal. You can enjoy flirting from time to time. She has trust issues now. However apart from letting her casually rifle through your phone, telling her about everything related to that subject and generally talking to her about it you cant do much.
Since she obviously now broke up with you, you should think about what you want. She told you to not contact her - which is something id only respect if i wanted it - or if I see fit.
If you want her back then you will probably at some point have to fight for her. Perhaps she even expects you to.
Maybe she also expects you to keep away from her, because it hurts so much - i dont know.
How long are you willing to wait?
How could you fight back for her?
What terribly romantic thing could you do for her - without contacting her (and with contacting her)?
If you think I am insulting you with my post or bashing you: You do not get the point.
I am not here to insult or bash anyone. I offer up my free time to help. Take from my post what is useful to you.
If you are angry about my post or myself, then please stop and think how that happened. Usually that is the way the brain responds if a critical belief system is challenged (its called cognitive dissonance). If you have trouble with it please answer in the thread. I will come back to you.
