Me and the missus broke up when we both went to different uni's, as we both decided that we didn't want to feel constricted. Reached my final year, we're both single after two and half years of other people, and we get back together after we realised that we were happiest together. Had a lot of fun with other girls, and my share of the requisite one night stands, but never met anyone else who made me as happy. It can work.
