Please help

So I've been dating this guy for a little over a year. He is my first boyfriend, first everything. He is the sweetest guy I've ever met and has always excepted me for me. We used to spend everyday together but then he got this new job, which puts him farther away from where I live, it was like he turned into a different person. He stopped texting me like he usually did during the day. He never comes to my house but is weird if I don't come to his(makes me mad). I've noticed through this relationship I've had unrealistic expectations of what a boyfriends supposed to be so I went with the flow. There is a 6 year age gap between us, me being the youngest. I have seen that through this relationship we don't really complement each other well. I can't read him no matter what mood he's in and he rarely smiles even when he is happy. He can't tell when I want to joke around or be serious. There are things I want in life and in a relationship that he's not doing and I don't think is capable of doing. He tells me he will always be there for me and that he loves me more and more everyday. I feel like he is completely oblivious to how I feel. I'm having a really hard time sorting my feelings cause I know I love him I'm just not in love with him and I feel after a little over a year together I should. The other part is I'm young and am spreading my wings(sheltered child)I want to travel and do things and he doesn't care to, he's set in his ways. I really need help on this cause I just don't know what to do.
