Actully its hard to compare girl friend and best friends. Best friends are either girl or boy but gril firend is specefic and its depeds upon you that how to handle the relationship. One thing is important and sure that girl friend is not  compulsory in life but without best friend we cant live and I think those persons are lucky who have best firend. In this matter I feel very lucky that I have very best friends ...if U have money U have girl fren but u dont make good friend by ur money, This isjust my feeling ,...so dont think negative and pease give your views,...thanks
