You really need to get a grip, is what you need to do. What is your problem about here having had friends or boyfriends in the past? This has absolutely nothing to do with your relationship with her. The sum total of her life and experiences in the past are what makes her who she is. If you like her, or love her, it is because of the experiences she has had and who she has become.
If you want someone who has had no life before meeting you, get used to being on your own.
