My girlfriend spends more time with here best friend than me
So I've been dating this girl for a few months and I really like her, we just got over some problems about spending too much time together, and so I gave her all the space she needed. She then told me that she wants to be with me and no one else, but now every time we go out she brings her best friend along, I feel like she would rather spend all day with her best friend than me, what can I do to get her to want to spend time alone with me?
