Is it really over?

I first met my ex- boyfriend six years ago and we have dated but it was nothing serious (a few weeks or so) but we have always been friends and a big part of eachothers lives… last year we started spending more and more time together and eventually started dating in february this year… we had so much in common, we finished eachother’s sentences enjoyed all the same things and had the same ideals and thoughts about everything,..like he was the only person who got me… we had our problems and fights but we always managed to get through it because we knew we had something so special. he always (for years) has said I am the girl he wants to marry no matter what happens with us now one day it would happen.. we started writing our finals (we’re in 2nd year varsity) a month ago and that’s where things went pear-shaped…we kept fighting about stupid things, we snapped at eachother and it just wasn’t pleasant but I figured we weren’t eating, sleeping or concetrating peoperly and that was it…so I finished my exams on monday and we started fighting when we went out and when we got back to his house he said he didn’t want to be in the relationhip anymore (he’s dun this before and we have gotten back together a few days later) he said I am his life and he loves me so much but he is not in love with me anymore.. I have booked tickets and paid for them to go away with him in december and we have so many plans for next year. I saw him yesterday and he held me and kissed me and said how crap this was and how hard it is but it has to happen… I just want to know if this is just a pohase he is going thruand he will want to be back together with me after a week or so or if he is really serious and it really is over??
