bf or marriage

My bf of 6 months decided to propose to me and I said no it's to early for me I need 1-2 years ... he told his parents that I don't wanna marry him so his parents found a girl for him to marry we dated for a year and now he has decided to marry her for his family ... I feel upset i told him I'd marry him now but his like his parents have decided and he will listen to him. 
I feel so hurt but for some reason i feel this feelings temporary becoz he was uneducated indebt etc while I'm educated
