Do you think she wants to break it off?

more or less i met a girl online a good few months back, things were great for the 1st month then we had a fight, shed been spending tonnes of time with this other guy and decided she wanted to spend an afternoon with him on a night we were going to spend together, i more or less told her im not going to stop you but it would upset me heaps if you did, and she did which nattrally made me feel horrible i talked to her the next day, and by talked i mean blurted like an idiot asking her what she was thinking and if she even cared about how i feel, she got angry took off and was unreachable for 3 days, then she came back we talked about why this happened and more or less both said sorrys, but when i asked her if she wanted to get back together she imidiately droped the convo and got upset when i tryd to bring it up, we were together dispite that and things went back to normal, then just recently shes had ALOT of time xtra at work and telling me she just isnt in the mood for being on the comp, and when she is on doesnt talk and gets upset if i try to tlk to her about our relationship often. i know this sounds silly because to me it seems like she wants to break it off obviously, but i want a few more opinions
