Am i in love or lost?

I love my boyfriend but i like my ex from almost 5years ago. I am a senior in high school, and i was in love when i met my boyfriend right now of one year and four months ago.His poetry sinks my heart, and he gets me.We never got into fights, until the last couple of months we've had our differences, but we over come them...But it's so repetitive, and alittle boring...And Right now i'm confused, it's like i love him but i doubt the factor if i am in love with him. He annoys me constantly with this sniffling/cough thing he does everyday when we talk on the phone. It never bugged me before, but now i'm just picking up on the negative he does, and the positive is still there but why don't i see it like i did almost a year ago.I was infatuated with him, but now it's the stage of where i really need to be committed,but i don't know if i want that...And the fact that my ex likes me again, and i like him, for we have had a mutual friendship two months before me and my boyfriend ever started dating..it's like a bend and a stupid twist in it. So the question is, what should you do if you have a really dependable boyfriend who loves you and an ex boyfriend who likes you? But if you have feelings for both.
