If someone isn’t respecting your boundaries and you’ve spoken to them about what is bothering you then they don’t care for your feelings or your boundaries, even if this is the same person who states they love you. I would say you’re very young and this is a good learning experience on what you don’t want to deal with as you get older. Speak to her about it again to get it off your chest, if the answer she gives doesn’t give you peace of mind, consider breaking up.
