Fall in love with my best friend !

I felt in love with my best friend who is 3 years older than me

We are friends about a year!

Now I haven't seen him for 3 month after days I understood can't live without him! But I can't say anything to him cause I have no idea about his feelings our friends told me he loves me but I don't know how to believe!

I don't know what should I do please help me!:(
