<human>: Could you distill the essence of the text into 1-3 sentences?

Me and my girlfriend are both 19 we had been dating for 2.5 years, she broke up with me and I don't know what to do.

She said she wants to be single so she is care free and can be spontaneous. She said for a while she has been feeling unhappy and she misses what we had and doesn't think we can be happy together anymore. I don't know what to do. I want her back and i want to call her or text her but I can't because I know that I must respect her decision. 

When we broke up we talked about it for around 3 hours. We have to see each other regularly because of school.
We are both 19 so I guess she just doesn't want a serious relationship right now. I don't blame anyone in specific but I know that a bunch of her friends and coworkers are single and she might think that their life seems much more enjoyable. I did talk to her about moving out together which may just have been too serious I guess. She said we are taking a break but I feel like she is just being nice. I know she doesn't want to keep me "hooked".

I want her back and don't know what to do. I cant really eat, sleep or just be normal it is probably because I am in shock still. It is possible that she reads this I don't know if she will know it is me but if you do. I miss you.
<bot>: My GF of 2.5 years broke up with me because she says she wants to be single and has been having more fun with friends then with me for a while. I want her back.
