My girlfriend graduates (early) in December, & goes to grad school in Colorado. I don't know if I can stay with her or not - it feels so serious like we're saying yes, I want to stay for good. I'm 19 - I don't even know my major, let alone who I wanna be with for good! And honestly, I can't see it being her, but I do love her & don't wanna hurt her. Also, this is the woman who stayed /w me through a nervous breakdown visited the mental hospital every day to see me. I feel like I can't leave her, even if my mind was made up. But such commitment is scary - it's my 1st relationship! Not ready!nP.S. I'm (female)
