Boyfriend drama?

Megan
My boyfriend recently texted me- "I've been talking to God a lot, I don't know if I even want to get married." It was never like this when we first started to date. We both knew in our hearts that someday we want to be married. We decided to date 3-4 years before marriage (year 2 coming soon) he says feelings haven't changed about me- he still loves me and is commited to me... But says he doesn't know about marriage?! Am I wrong for kind of being sad/mad about this? We are both strongly involved together as Christians and in God- but I don't understand how or why his feelings changed? Can anyone help?
