My girlfriend isn't verbally affectionate. Does she love me?

She knows I'd love it if she can be a little more verbally affectionate. I've asked her many times if she can express her love verbally more frequently but she still wouldn't do that for me. I never hear an 'I miss you' or 'I love you'. I'm so disappointed so I've given up.

Why can't she do such a simple little thing that can make me feel loved? I love her with my whole heart but it hurts me to see that she can't even do something simple like that to make me feel loved.
