i don't know what to think, should i let him go

don't depend on him in what ur gonna do with ur own life. figure out what u want and he'll have to accept it. if u've already told him that u want to be together, and he gives u the silent treatment, then there is ur answer. tell him u don't have the emotional capacity to play these head/heart games. if he can't answer u then his silence surely spoke for him and leave him be. i've been there and sometimes this is the only way. i know it's very painful to break away from someone u have such a strong connection with but u'll be ok. nothing in life lasts forever and all we can do is understand and accept. u'll have ur memories and the good times that were shared. they are more important than u know. be glad for the time u did get to spend with him and grow from the experience.
