I’m so confused!!

I am 16 years old since August. I’ve been with my boyfriend for 6 months. He is a genuine absolutely amazing man and treats me with so much respect, and realistically we kill each other but I want to marry him and have his children. Sometimes and some days I want to break up with me and become confused and sad, but yet I can still picture myself marrying him. I’m 16 and I want to break up with my boyfriend often, yet I can still 100% picture marrying this boy. Sometimes I want to go off and be a slut as I’m young and wanna have experiences, but I wish he could still be there waiting for me and marry me in the end.
