So I've tried working things out with my boyfriend.. things were going good but then they started going downhill again. Its not him this time though its me. When he's not around I feel like I miss him and everything but then once he's here I feel like I rather be alone. Like he bothers me or something. We haven't had sex in about two months. That's my choice though. He had told me a couple weeks ago that he didn't know if things were going to work out or not because we don't see each other as much any more and stuff. But I feel like we don't need to spend every minute together or be having sex every day. I'm still really young.. sex isn't the only thing on my mind. I just don't know what to do because I feel like I need time apart but then I feel like I don't. I feel like I'm contradicting myself. I love him but I just feel really confused. Maybe I have the whole thing that I'm use to having him around and letting him go will be hard because he's the one I've had in my life for 4 years. I need help though. All of this is stressing me out. I don't know what to do or what to say to him. Someone please help

Apparently you feel comfortable with this guy after 4 years but have serious problems. Would suggest that you find someone else if you are that upset that you feel uncomfortable around him. Basically he's become a habit and nothing more.

There is nothing written in stone that says because you are with someone for 4 years you will not grow out of them. This happens quite frequently especially when you are in your teens.
Take a break from each other. People do it all of the time.
You may find someone else or you may find you are quite comfortable not being with anyone.

Maybe its time to end the confusion, and take some time and space for yourself. Yes you just may be comfortable with him, but its causing problems that the two of you can't deal with.

That's when its time to change the scenery.
