Call your girlfriend. It's time you had the talk. Tell your reasons. Say it's not her fault, but you just met somebody new. Don't you tell her how I give you something that you never even knew you missed. Don't you even try and explain how it's so different when we kiss. You just tell her that the only way her heart will mend is when she learns to love again. And it won't make sense right now, but you're still her friend. And then you let her down easy
