Me and my girlfriend was having a wonderful time together and we both love each other deadly. But today I woke up and she was acting strange. So I just went with it but when it got through the day I got worried about it . So I ring her up asking if there is anything wrong and she says there ain't anything wrong so I was happy with that and later on at night she rings me up saying I'm going to Brake up with u because I don't feel like being in a relationship at the moment and I need some space . And she said to me that she still loves me and that and I love her too and she said she will get back with me, but I'm not sure what to do, someone please help?

No you don't "BOTH" love each other dearly, and no things are not wonderful, they may be for you, but not for her. She is having issues and problems are she would not want this.

Almost always, "I need space" means she wants out of the relationship, she is only being nice, trying not to hurt your feelings too much or end up in a fight over it.

You can assume most likely this is about over. And need to address it from a serious issue you are not aware of
