need inspirational feedback

My boyfriend of a year, whom I thought I'd for sure marry, is starting to show a different side of himself. He use to be cute and romantic. I'd catch him watching me and he'd say he didn't know how he got so lucky to have me. I couldn't tell you the last time I heard that. He's not affectionate anymore unless I initiate it. He never tells me I'm pretty. 
I don't want anyone to tell me I need to find someone better. Don't tell me to move on... I already believe that's what I'll be doing soon. Or trying to do. 
I want some stories of ladies who have been in this situation and worked things out. I need some happy ending advice. Please.
