Should I break up or continue?
Well I told my BF that one of his female colleagues and friend looks flirty to me (since she used to give flirty comments on his Facebook profile). Prior to that I even questioned him who's she when I saw the Facebook comments. He told me that she's a colleague and friend. I said "ok but if anytime in future you like someone else you'll tell me right?". He said he'll tell me and that it will never happen and also assured that there's nothing going on between them.
That was fine. So the next day the topic somehow came up again and I said she's flirty. At this he talked to me in a nasty tone, almost shouted, just that he didn't raise his voice saying "oh come on mannnnnn!!! you dont know anything about her ok" in a nasty tone I've ever heard from him talking to me and went all the way to prove how nice she is and how she's always talking good about me when all I can do is talk bad about her. The next day I thought about it and wrote a break up email saying that "this wont work out coz if u can talk nasty to me for a simple reason as i called a colleague of urs flirty, someday in future i may not like something about some of his friends again, u can't talk like that to me everytime, Im the girlfriend!! It seemed like Im no more important than that girl in your life". So he doesn't want to break up and told me to take a week's time and think over it and let him know next week.
Im not jealous of that girl, I could have let him go for her if he liked her but I now know that's not the case. But problem is Im nothing more important than any of his friends, Im at the same level or even lower than them in his life (of course he says its not true but is obvious when he almost shouted at me in a nasty way just because I said she's flirty). Worst part is that he thinks he did nothing wrong by defending his colleague (be it in a nasty tone). So is this relationship worth trying? I have a week's time. So please help me out.
Some of the important facts... I did not accuse him of cheating. I just asked who is she. I was convinced to what he said above. And I never told him to stay away from any friend of his not even this girl
