No clue why...

We only dated for about two months, but I've had a crush on him forever. I messed up badly and he ended things. Yet we've both agreed that we weren't ready to stop seeing eachother and we still have feelings... Ive been in longer relationships and I still haven't felt this way about anyone. Is it cause the breakup was my fault? It just feels like there's a piece of me missing now and I have no clue why he affects me so much when he was around for so little of time...
