Dilemna of the HIGHESst standard

Okay.... so um I have this love problem and I was hoping for some help.
I know I haven't posted much on here but I don't know where else to go.

So theres this guy, lets um call him Boy A (um Andy) and the other one lets call, boy B (Ben). okay?

So in September I met Ben and we were in a school team together and grew very close, and I developed a crush on him, but then after the season ended we kindof drifted apart and didn't really talk. I still really liked him, and whenever I saw him my heart would skip a beat and I'd remember all the good times we had together.
So at the start of the new semester we had the same class together, (instrumental) and I was so ecstatic to be with him and... it had grown awkward between us. I didn't know what to say, or to even have a long conversation with him like I used to.
So then I met Andy, who is also in my music class and we grew close because we both like anime. He practically texted me every day and was really nice. Then when the girl he liked said she liked his best friend, he helped her get with him.
Then Andy found out I liked Ben and he said he'd help me out. Along the way he's been dropping hints that he likes me and I just kind of ignored them.
But when we went as a group to the movies, Andy was pressuring me to confess to Ben, but I didn't get the chance.
Then on Monday, I realized I was beginning to fall for Andy, who I have only known like a month and I just don't know what to do.
I was going to confess to Ben this week, but now I don't know if I should!!! Andy is the nicest guy ever, he's sweet, sensitive, and he really cares about me.
Ben is so much fun, he always makes me laugh and we have a lot of similar interests... but I'm pretty sure he only thinks of me as a friend.

Then today, Andy came up to me and asked for some advice, "This friend of mine is helping the girl he likes to be with his crush and he found out that her crush doesn't like her back, should I tell her?"
"Are you talking about yourself here?"
"Yeah. so should I tell her?"
At that point obviously I was thinking it was me... I mean its kindof obvious, and I accidentally mentioned Ben and then the bell rang and we left school.

What do I do!? I was so sure before that Andy was just a friend, and that Ben was the one for me, but now I just... DONT KNOW!!!
If I confess to Ben feeling like this, and he says yes, I don't think I could build a healthy relationship.
But if I choose Andy, then I can't be with Ben who I have liked for months and months and I don't know what to do!!!

Plz help?
