Every time I expressed my feelings for her she always said how she didn't know what she wanted and that she didn't know how she felt about me. She started pushing me away more and more and about a week ago she pretty much just started to ignore my texts. I acted way too needy at this point, sending her flowers and stuff. I then decided that the only thing to do was to put the ball in her court, telling her to feel free to message me if she ever wanted to talk again, and just leave it at that.
It has been almost a week now and she hasn't contacted me at all. There is such a huge temptation to text her but I know it will just make things worse if I do. I am desperately trying to get over her but I just can't stop thinking/dreaming about her and regretting some of the things I did that drove her away. Is there any chance left?
I have also noticed how rapidly my mood has been changing over the past few days. occasionally I will be unusually motivated and in high spirits, but this can sometimes only last for about 10 mins, sometimes longer sometimes shorter. The rest of the time I will be extremely unhappy and just think about her, even when I'm out with friends or busy doing other things. Why is this?
