How to divert myself?.What should i do?

My boyfriend after 3 yrs of expressing love to each other says,he is infatuated and not in love with me.I love him so much.He asks me out about whether other girls accept him or not.It's really paining me,when he questions this.He knows that,i love him n still he raises about other girls.Friends,plz suggest what should i do?.Shall i forget him or will he ever want me and love me?.It's very hard to forget someone when we love.Suggest me something that,i should never contact him again.How should i divert myself?.
