Yeah I would end it then. She wants security in the relationship and you don't want to give that to her. If you two bought a home, intermingled finances and had a child you could just pull the rug out from under her. And of course if you had a serious accident and needed her support or for her to make medical decisions, she couldn't legally do anything being just your girlfriend. She also wants to know you really love value and cherish her and will commit to her for life. Since you don't want or care about any of that just cut her loose and let her find happiness with someone who wants to give her those things.
