A similar thing happened to me before my ex went uni. I said we might not work, he thought we wouldn't and dumped me. It seems like a quick decision, but then he ended up askin me back and i said no! Took me a while to get used to being without him. I just texted him once to say thanks for everything and never spoke to him till he rung me 3 months later. It was ok cause i was away from him. I just went out with friends and found things to keep me busy. I cried when i needed to. But after a couple of months i was ok. Then i saw him, 6months later and had realised i'd moved on 100%. Now, i've got another boyfriend who is utterly perfect. When you break up with someone and have time to think about things, you realise what was wrong with the relationship but you didn't wanna admit to yourself cause you were dependant on that person. At the time, i thought i was so in love, but looking back, it wasn't that great and i was never really that happy, but i was scared of losing him. I'm a much stronger person because of it. Just hang in there, everything will be ok.
