Is it Over?

Me and my girl had\have been going out for 5 months. Today she said she wants to have a break as she feels we are just doing the same thing all the time. She says she still loves me and wants to be with me forever but thinks we need a break and a fresh start. Personally i think shes confusing things getting stale with just settling in as of course relationships get less exicting as time goes on. I really hope we get back toghether as I cant imagine life without her but Im worried while where on a break she will find someone else, or realise she just prefers to be on her own. Any advice, do you think this is the end or what?
Btw i am 2 yrs older than her I am 17 she is 15. Tweet
