15&inlove?

I'm 15 and there is a boy I recently dated let call him "Steve" I really like Steve I would get a weird butterfly feeling in my belly when I seen him or even thought of him but we broke up and I was really upset but I didn't wanna show that I missed him and then I started to get really close to his bestfriend let's call him "Freddie" so then I started to develop feeling and then he went out with my friend and I was upset about it but after awhile they broke up and me and Freddie started talking again we go a little to close and then the other day I was sitting there in bed at 4am thinking I don't actually like Freddie I really like Steve and then I was talking to my bestfriend Megan and she suggested I might be in love I scared that I won't move on Iv tried taking to Steve but he would just give me one word answers so I just gave up in the end. PLEASE CAN I HAVE SOME HELP!!
