<human>: Can you condense the text into three sentences or less?

Edit: sorry I haven't been on this subreddit before and didnt know how to post properly. I am m(22) and she is f(30)

 So tonight my girlfriend mentioned to me that she just isn't feeling it anymore. We've been dating for almost 2 years now and living together for about a year and a half. It hit me like a tonne of bricks and I just shut down. She was on the way to the movies with her friend and I was admittedly a bit upset so she texted me saying she wasn't feeling it anymore. Apparently for the last few months she hasn't been happy and just has given up. I went to her to talk but she didn't have much to say besides that she was going out. Her friend picked her up and now in left waiting until she gets home to talk. I just don't where to turn, I don't normally ask the internet for advice but I don't know what to do. 

I am thinking of how to try and recover from this but I don't know if we can. I think she will just give up and not be open to try anything to help, I was thinking since she missed the times when we first started dating that if i moved out and we kept dating then maybe it would bring it back to the old days per say. I don't know of I'm asking for advice on the right place but id love any asisstance.
<bot>: My girlfriend sprung it on me that she isn't feeling the spark anymore and I don't know what to do. Serious sggestions greatly appreciated.
