<human>: My girlfriend of 2 years blindsided me with a break up one night. It's as if over one night the "I love you" meant nothing. 

Throughout the summer we had been bickering and butting heads somewhat frequently but nothing ever major. I work an odd work schedule but when I was at my house she was there nearly everytime. For a few months we had been looking at rings and talking about marriage. 

I was buying the ring next week and had the whole proposal planned out. 

Shes going through a stressful time in nursing school and I will admit that I didn't help that stress level. We began to have communication issues but nothing we couldn't have worked out. 

She said that I have been smothering her and that she needs her space. 

We've been mostly NC except that her grandpa fell and had surgery at which time I contacted her to find out what room he was in at the hospital and went to visit them when she wasn't there. (I got permission from her to see them.) I thought Id be marrying her and already considered them family. 

She gave me the whole "I'll always love you no matter what happens."

So what do I do? She said she needed her space so like I've said, I've kept contact to a minimum. It's just killing me not seeing her and not talking to her when I felt we were so close, but she seems to act like it was an easy decision. At some point do I contact her or just wait and see what happens?

Give me a shortened version of the text
