Thank you for the thoughts. I have wondered whether there was something I did that made her change. But to my knowledge she'd been that way for a long time and I was weirdly a little flattered that I was a guy she could love. I really don't doubt she did love me for a long time. I've never really beat myself up over it. I've wondered about projection but I don't really know what causes it to arise. Really my worry is that these are perfectly common symptoms of dissatisfaction and unhappiness alone and I am too dense and cowardly to admit it. Many days though, that seems completely absurd and I know I want and love my girlfriend.
