bf is already calling me his wife/mentioning marriage??

my boyfriend and I have been together for around 2 months now and I really like him a lot. things moved kinda quickly bc he's in the army (he goes to west point). anyway, he's already kinda mentioned getting married and he's mentioned me being his wife a couple times as well. I think it's really cute but obvi taking it with a grain of salt. is this normal/does this mean anything? my only other relationship was for 5 years and we obviously talked about that stuff but it was more serious bc of how long we had been together.
