<human>: Can you succinctly summarize the text in 1-3 sentences?

So, me and my boyfriend have been together on and off since I was a sophomore in high school, but together completely for the past year. I used to be completely obsessed and infatuated with him, but lately things have been so different. Everything he does irritates me and annoys me, to the point where people have commented that I snap at him and give him attitude a lot, which is odd because I have never been an easily agitated person. I still love hanging out with him and feel more comfortable with him than anyone else in my life, but he just irks me constantly with the little things he says and does. 

The biggest problem that has been going on is one that has to do with out sex life. I have always been a very sexual person and loved hooking up. We used to have incredible sex every day, and now we do it once a week at most. And when we do, I hate every second of it. It's forced and I am not turned on at all, and am pretty much waiting for it to be over. We are so young and I feel like we are too serious and too close and our relationship has become boring. He is my best friend but I am now doubting whether or not he is meant to be my SO. I want to have sex with other people, have my freedom, and be single. 

But there's another part of me that thinks I'm wrong and doubts myself. A few weeks ago I sort of talked to him about all this but ended up freaking out and getting upset, and changing my mind because I have a fear of change and thought maybe I was being ridiculous. It's so difficult for me to think of being without him because he's been such a big part of my life for so long. 

I truly am at a loss. Should I break up with him, should I wait it out? It's been a really tough past few weeks thinking of all this.
<bot>: I no longer feel the attraction to my again/off again boyfriend of four years, but still love him a lot and feel like I might just be acting stupid by feeling this way. I am hesitant to break up with him.
