how to make a lover to a wife

follow her everywhere, take care of her, and make impression that you

You can not force someone into marriage if you want your marriage to last. I could suggest that you refuse her something that she presently gets that is normally between man and wife but that is not right and is not a good basis for a marriage. Instead of assking her to marry you ask her why she doesn't want to marry you right now. Either she doesn't see you as a life-long partner or she is not ready for marriage or she is still unsure of everything including your relationship. If you love her, respect her reasons. If she tells you that she doesn't see her life being with you forever, then maybe it is time you break off with her and find someone who does want to be with you forever. Just don't get her to marry you for the wrong reasons.
