Im so scared of getting my heart broken?

i have been absolutely in love with my best friend for over a year now. his name is ben. last night me, ben, elena&danny(a couple) were all at danny's house. me and ben were sitting down next to them and they were cuddling. ben started to put his arm around me and i leaned my head on his shoulder. he told me he's really liked me for a couple weeks and i told him i really liked him too. he was texting me that night saying how happy he was when i put my head on his shoulder because no girl has ever done that to him. believe me i know how he feels about me because he tells me a lot and he always compliments me. he also told me how scared he was that i wouldnt like him back. i love him..a lot..but im sooo scared of getting my heart broken. what do i do?
