I'm in love with my best guy friend and i told him?!?

I told my best guy friend that i was in love with him the other day, his reaction was not what I expected. He seemed slightly shocked at the fact that i love him because he always suspected that i liked him but, nothing has changed between us. i have never met him and i have only known him for a few months but it feels like we have been best friends for years. I went on holiday 4 weeks ago and before i went on holiday things were perfect, we spent everyday texting and ringing each other and we went on cam every single night for hours on end. We used to spend hours and hours on the phone every day, one day he rang me 6 times in the space of 6 hours! We had sweet talks, we flirted, we had little personal jokes, we always messed around saying how much we hated each other but then he would say i love you too or you know you love me really. But, since i got back from holiday things have been different and I think it is because he met a girl on the internet whilst i was on holiday and now she is the girl who he rings all the time, texts all the time and goes on cam to all the time. It has been horrible since i got home so i gave up speaking to him, or if i did speak to him i wasn't myself, i was very blunt with him and he knew it. At one point i did say i’m done and i told him not to bother ringing me because i wouldn't answer and not to bother texting me because it would remain unread but then he decided that he didn't want me to leave his life and he started being HIM again! He rang me but i rejected it but he rang me again so i answered and went what and he spent 5 minutes apologising over and over again for treating me like dirt and then he spent another 10 minutes just talking to me like we used to. So i got fed up of all the messing around and on Wednesday when he asked me if i liked him as more than a friend i said im not telling you because it will make things awkward, he said it won’t i promise b (b is his nickname for me, along with babe and hun and hunnie) so i turned around and went yes i do, I LOVE YOU! and he just acted like normal. I sent him a lot of things which i have written on a website about him and he read them all. Then the other night we were speaking and we have decided on a fresh start, we are starting a fresh and i told him to forget what i said and he said no he isn't going to forget it because it isn't making things awkward. So now we are starting a fresh and going back to the way things were before i went away, or at least we were supposed to be, i don't think we are going to be ringing each other as much, or texting as much or going on cam because he is supposedly 'in love' with this girl that he has known for 3 weeks! So please help me! What should i do? I’m in love with my best guy friend and i don't know what to do, i’ve been told by 5 people that he likes me and one of those girls is one of his many ex girlfriends. Also i get asked all of the time by my friends when me and him are going to get together. Another thing that is confusing me is that i told him everything my friends have said, about him liking me and us getting together, and he didn't deny any of it, in fact! if anything he avoided saying anything about it but he made certain to comment on that fact that my parents thought we were in a long distance relationship! I just don't get why he would specifically point out what my parents said but try and pretend i hadn't told him what my friends had said, all he said was he was shocked and speechless! so once again please help me, i get this is confusing to understand but any advice will be greatly appreciated!
