Big red flag from my experience. Usual indicates poor emotional boundaries. Proceed with caution. Do your due diligence. Learn all you can about her before you commit any feelings... her past relationships, her current friends, how she gets along with family members, any history of abuse in childhood, how she treats others, is she taking the time and effort to get to know you? Things that seem troublesome early on in a relationship usually only become worse once a person really starts to relax and show their true colors. Once she earns your trust, she is then deserving of greater and deeper emotional investment.
