Is it normal to feel this way about my boyfriend?

Alright.... Well me and my boyfriend have been together for four months now, I met him through his cousin who's my friend.
To fill you in on some, he had been after me sense last year, but I wasen't really into him or even really knew him. So I kinda just did what every girl does do an unwanted guy-respond to their text messages an hour maybe two hours late, then make up some lame but belivable excuse on why I was responding so late. Or just ignore him. But then he did'nt text me as often wich I liked but didn't. I felt weird. Weird as in why hasen't this guy asked me how my day was? Or if I'm ok? In other words I didnt like feeling unwanted.
Then after the summer ended I started texting him, and he would always respond. Eventualy I told him I kinda digged him, he immediately claimed that me and him were together from that point on, wich kinda bothered me becuase it was a desprate guys move but I didn't give it to much thought. Now four months later im miserable. I don't want to be with him. He's so clingy. And on top of that he loves me, I feel so bad that I don't feel the same way about him. And hes also hideous!
I have no idea what to do. Might sound stupid, but I try to find reasons to break up but can't! He's not rude or anything. I did break up with him once but he begged me to come back to him so I did becuase I felt sorry for him. I just don't know what to do. I feel like iv'e wasted 4 months of my life with this person! Is it normal to feel this way? Does anyone else understand what I'm trying to say?
