Girlfriend seems a little too attached, too soon. Should I be concerned?

You should definitely talk to her about your feelings towards her but you should mention that you feel that she's a little too invested in the relationship, especially at such an early stage. Let her know that you want to be there for her but you should tell her that sometimes you both need your own space. Make sure not bring this up during an argument or fight because typically one may say something they don't mean that could be hurtful when angered. We hope this helps! :)
