If you're coming on way strong at just 90 days into this she probably doesn't mean it as a good thing when she says "she has never been loved the way" you "love" her. Three months is still just very much in the tentative getting-to-know-you phase of a relationship so if you're throwing around the "L word" and acting like you two are getting married of course she's freaked out. On top of that she's 22, meaning you almost certainly won't be the last relationship she ever has. Check yourself because this would all be way too much for the typical early 20's person only a mere three months into seeing a new suitor.
