Is he serious about me or could he be using me?

I have been dating him for roughly 6 months. We are both in our mid-late 20’s. The first 3 months were ok, kind of awkward, but over the past 3 months, I would say we are getting closer, talking almost everyday and seeing eachother everyweek, sometimes 2x a week if our schedules allow. He’s extremely affectionate and complimentary- always telling me how sweet/amazing/beautiful/hot/y I am. He always tells me how much he misses me when he’s on the road for work. He has even drunkenly chosen our wedding song and sang it to me, if that has any relevance, haha. He is quite amazing himself, no one has ever made me smile and laugh like he has. I love his personality, and he really inspires me to become successful in life. Our life is pionate and mind-blowing...unbelievable! I feel he has fallen for me, but I’m too scared to ask how he feels. His actions prove that he is- this past weekend, he unfortunately had to work one morning, but he pressed the snooze on 4 times b/c (cont)
