<human>: Hello all.

I felt there is something wrong a week and a half ago and eventually provoked her telling me what it is.

She broke up with me three days ago. We were together for two years, 4 months of which we (successfully) went through a LDR.

She told me she didn't already feel the same for me, and was worried she could hurt me even more by going on. My reply was that this could not go on without her being serious and responsible about her decision. She seemed very hesitant actually saying it's over, stating she would be very happy if she could just make up her mind and not leave me.

Now, I haven't been the perfect boyfriend (no cheating or anything serious, but several arguments and generally being careless at times) and was heavily engaged in work/studying which was the reason for us to be seeing each other not as often as we would like to or had previously. I do believe this has affected our relationship greatly.

This whole situation is very confusing to me. I am not sure whether she actually feels this way or she just wants to test my reaction and decide whether it's worth the trouble. Is this wishful thinking?

We still do keep contact. In fact, the very first evening after we met and paired our ways, she IMed me, asking me how I felt and was concerned about my well-being. 

On the second day I foolishly got drunk and did the same. She eventually invited me to her birthday party, explaining she would understand my decision, no matter what it is. Her explanation is that she would be happy for me to join, as I am a still important to her.

I am quite sure she's going through a hell of emotions right now, too and doesn't take it all lightly. 

If I had a chance to win her back, I would take it. Yet, I am not entirely sure whether it is sane to dive into another vertigo of emotions, because this would devastate me.

Provide a brief overview of the text.
<bot>: She broke up with me, but I don't think or accept it's really over. Should I try to win her back?
