should i stay with my boyfriend?

Im a 16 year old girl and ive been with my boyfriend for almost 3 months. im just feeling really confused and looking for some good advice please dont judge me for anything i say. At the moment i just feel like i dont want to be with him anymore he was really sweet and nice when we started go out and i really liked him but now the things that he does just annoy me and he gets on my nerves a lot. Dont get me wrong, he is a really nice guy but at the moment i feel as if i try and tell him all the thing he does that annoy me he ould have to change to what i want him to be and i dont want to do that i woud rather just like someone for who they are already with out having to change them first. I know most of the reason for me not wanting to be with him is becuase i feel like i have commitment issues and like with most guys i have been with i feel like he is too clingy and he probably isnt its just me thats scared of being that close with someone. I have also gain a lot of new friend through going out with my boyfriend and im scared i will lose them all when i break up with him.Another reason is that i have feelings for a guy that is my boyfriends friends friend but i know that if i break up with my boyfriend i porbs wont get to see this guy again so either way i will never get a chance with this guy. The whole point of this is really me just looking for some ways of telling whether i should stay with him and work it out or let him go and find someone else. thanks you so much for reading this whole long thing it really means a lot. xxxxx
