miss my ex

I dated this guy for a year or so and we didn't have sex, but we did other things. I broke up with him over something stupid and when I waned him back he didn't want me. he found a new girlfriend and it kills me seeing them together because all I want is him, I wanna be able to lay in his bed with him again. I just want him back.. I need your advice girls, do you think I should stay single and wait for him to come back or should I move on?
