I find you an Honest John here, dear, in openly admitting that You------Want out of my relationship. You realize right now that you do Not want to be in a real relationship anymore and that you want to tell her, no matter when it would be.
No time is the right time, 'Spring break' being no exception to the rule of thumb. However, Telling her, the manner in which would be the most Appropriate, is something of another subject matter.
Don't text her, you need to see her alone, face to face. You both need to sit down and you need to lay your story on the table. Tell her how you feel, simple as that.
Drive over to her house and ask her to come out to your car. This is a private matter and you don't want to involve her family.
I am quite sure it will take longer than a 'Week to get over the majority of her shock.' However, taking Spring Break to herself will begin her healing process so she can begin to lick her war wounds.
Think this over carefully before you make this move. Keep away if you decide you want 'Out' and no contact if all possible. Dangling her on a shoe string with even a Friends with benefits offer is also no good. If you are going to do this, make it a clean break, move on and if it is meant for you both to end up as friends, then so be it.
Good luck. xx

Just be frank with her, and honestly tell her that you don't feel love for her anymore. She will obviously be hurt, but it's much better than beating around the bush which would obviously hurt her a lot more in the long term.
