He Loves Me Much But I Never Let My Feelings Out To Tht Person Becoz Iam Afraid Tht I Wud Marry This Person Or Not.How Do I Tell Him Not To Kiss Or Hug Until I Marry Him?

He often asks me whther i love him or not.i avoid him saying tht i cant say.But in real i love him but problem is whther i wud marry this person or not .when i tell him he says tht will convince and make my parents accepted but long time back he said tht he cant marry me becoz of some circumstances.Now he says tht he wud marry me and want to be with him rest of the life.The moment i meet him the next day he says tht he is missing me.He respects me.
