I know you want to have her back, but if you were to have her back right now, it would just end badly for you. Trust me on this one. She's hurt, confused, upset and nothing good can come of that as a reason for starting a relationship again. This is what she wanted, she's facing the consequences and she's facing it on her own. It's scary for her. If she really needs this time on her own, she should use it to really take a look at herself and gain a little perspective. It's not easy when she's in the emotional shitter right now but you have to be strong and resist this. If anything, you'd be taking her back because you feel guilty and don't want to see her like this. That's not how your relationship started remember? It's not a good foundation.
Relationships are hard work and take a good deal of commitment and effort. But they are well worth it in the end. If she doesn't want to put forward that effort and instead having her own time and her own fun, that's what she wants. Currently she's torn and she would like the best of both worlds, you whenever she is feeling lonely and when she isn't, you to disappear. And we all know how that works out in the end. Not good.
Sorry if I make relationships sound like a job. They are in a way, but they are also very fun too. Don't forget to have fun with that special someone.
Waking up next to a beautiful girl,
Step outside and say hello to my beautiful world.
