Dumped

So, I had a lunch date with my girlfriend of two and a half years earlier today. Little did I know that that would be the last time in the foreseeable future that I would have a girlfriend. After I had finished my sandwich she told me that she hadn't asked me to come just for small talk and whatnot, and that she had something to talk about and to please let her finish before saying anything. I listened silently in concerned anticipation. She started talking about how she felt that we were growing apart and that we haven't been as happy as we have been in the past and we've been getting in little arguments over nothing and that the relationship has been putting a lot of stress on her with it being senior year and that she does not want to be my sole source of happiness and that she loves me, but that she thought we needed to break up. I ask several questions and she said that if I need time and space that she is willing to give it, but she wants to remain friends and that she would consider giving us another go in the future, but that we are officially over. She is my best friend. I let her know that. Everything is going to be hard, but I hope everything works out and we can get back together. I will remain hopeful. I love her. I love her so much. I'm so confused and conflicted. I guess I'm posting this here because I crave empathy and advice, and maybe because I may not be around as often as I was planning because I... I don't know...
