Hello Kyte & welcome.
They say that the child who is given freedom by the parent will always come back. Maybe it's the same with girlfriends & boyfriends who feel in need of a break. You will have to give her some space. As Peanut and Bella says this 'will either result in the two of you back together or with a complete split up.'
This very same story is told over and over on this forum ~ take a look through and see if you can get any ideas about how you should behave.
I'm wondering how old you are ~ age can often ~ not always ~ be a major factor.
Whatever happens remember ~
~ You would not really be happy, even with the love of your life, if she were not happy with you.
~ Time heals
Youngsters and unrequited love are the story of many a hit song. It is difficult to deal with, especially when ones emotions are all over the place, but it is true that 'there are other fish in the sea' and that 'time heals'.
Whatever happens, you will be fine. It may take a while to come to terms with the results, but you will sort yourself out and be OK.
