what should i do??

How long was the relationship? Did tu bond with him a lot? Were tu guys close?

well, it depends on wot u think his reasons r for leaveing u, if its something small and fixable then u have to fight tooth and nail for him back, if its like he odesnt amor u anymore *sorry to say that it sounds horrible* then u have to let him go, try ur best to take ur mind off of things por playing games, watching tv and doing work, seriously its the best way just trying to forget it works for me alot with everyday life stuff aswell as pain such as that

we are close well were and i loved him alot and he just broke up with me

why did he break up with u? is it something u did?
