Jack and Mary broke up .   it ’ s so sad . They had been together for only two months . Do you know what the matter was ?   Mary said Jack was cheating on her . Jack was seeing a girl from his hometown . One day , Mary saw them holding hands and ended the relationship immediately .   really ? I ’ m very surprised . He doesn ’ t look like a guy who ’ d ever do that sort of thing , right ?   no , he doesn ’ t . Anyway , she found out that he had been two-timing her for a long time .   maybe it is for the best . They are not suitable for each other because they have nothing in common and are completely different people .   how so ?
