I absolutely hate when people break up with you and give you the "maybe one day in the future we can be together again" line. It's incredibly egotistical and cruel. Also, it's unrealistic. Nobody has the right to keep another person on reserve just in case they find themselves being lonely later on or in case they've not found anyone better. Because that's all it boils down to. If someone wants to be with you, they should be with you now and not at some point in the future. That's ridiculous.
I know it's hard but you should do your best to move on. Do you really think it's fair for you to basically wait for her? Especially considering that by the time she's finished college, she might have already found someone else? No. You get over this egotistical brat and find a woman who truly wants to be with you. Now and not at some point in the future when it suits her.

Sounds like she wants to play the field while keeping you hanging on as backup in case she decides that she can't do any better.
There's really no valid reason for her to want to "tenporarily" break up.
