If she did that 12 days into your relationship it wasn't as if you had gone really far, would have been easier to have dumped her then, sorry for being so blunt. But if I were in your position I would have done the same as you have done, because I can't let something go which I care about.
One of my friends kinda had this problem, but it wasn't with her boyfriend threatening to break up with her, it was just his attitude towards male friends and her exes. She didn't talk to any of her exes any more, except for one who she talked to briefly and, for the first 2 weeks of her first relationship, said to one of her friends he thought he might like her again. He had hurt her a lot in the past, thank God she thought it was hilarious and sad.
Anyway, her boyfriend was jealous of me, as me and her were really close. She used to come over my house or I go over her's after college (I am the year above her, and this is the British education system), and we wouldn't even do anything that would make people suspicious; all we did was play Halo, watch films or just go on mine or her laptop and stuff. The first time I saw her after they started going out, I was over her house and he said that he wanted to talk to her on MSN while I was there. I was helping her revise for her Chemistry tests, but I understood him wanting to talk to her and stuff because they had only been going out a couple of days. A month later, however, she came over, but the day before she had told her boyfriend about this he said that he wanted us to be on webcam while she was over my house. I said OK, and so we had our webcam on at my house. He looked very moody, and she even commented on this. After this happened, I rarely saw her. Saw her at Christmas and me, her and some others went to the cinema from time to time, but she always had plans whenever I asked to meet up at other times. I didn't see her for two months at one point, and when you go from seeing each other every week to not seeing each other for two months, you know something's up. After their break up, I asked her if he was responsible for her absence from my social life, and she said 'Well, we didn't see each other for two months, did we?'
Sorry it's a long post, but you have to understand how someone who doesn't even have an interest in someone can feel if someone is jealous of them, and prevents them from seeing one of their mates. Think about how her ex might feel, but then again, if he is a douche and has tried it on with her, then you are right with being annoyed with her seeing him. If, however, it is unpreventable, like if they are in the same school or something, you'll just have to live with it. You can't control her whole life.
