<human>: Can you condense the text into a few key points?

I've been dating this girl I met 16 months ago for nearly a year (less than a month away from anniversary). It's mostly been a long distance relationship since I was away at college, but we regularly talked/skyped. Recently (after I've been back 2 months), we got in a short string of a few arguments but settled them. Maybe I'm just being over-paranoid, but it seems that we now treat each other more like close friends than boyfriend+girlfriend.

We do see each other semi-frequently (about 2-3 times a week), and we kiss and occasionally have sex (only I initiate, but she does invite me over). Yet, we don't seem to talk about anything besides friends/school. She also never says she love me, except when I tell her first. I feel like since we've been dating this long, I should be doing something different than I did 10 months ago. I don't want to question her about our relationship and ruin it since our anniversary is so close, but am I at fault for not trying to be more romantic or something? Or is it that we are both still immature?
<bot>: Dating for nearly a year, but relationship seems shallow and we seem like friends. How do I remind her that I'm her boyfriend?
