What does it mean when your boyfriend doesn't say "i love you" anymore??

So my boyfriend and I have been together for a little over 2 years now. We've been living together for about a year. I've noticed he never really tells me he loves me or say all the sweet things he used to say before we started living together. We do tend to get mad at each other more than what we used to but we get over it right away... I've become very insecure about myself and often end up crying myself to sleep because I feel unloved and unwanted....

Could it be that he doesn't feel the same way about me anymore??
