I feel as though I've gone cold to my girlfriend. I feel as though I still love her and a lot of the time when I think about her, I feel it, but when I'm talking to her, sometimes I feel cold. She's o perfect for me in every way, so I just can't wrap my head around why I feel like this. It's been going on for 3 to 4 months now. I think I might be depressed, because it doesn't make sense to me why I'd feel like this about someone who's so special to me.
