I am currently 20, and he's 22. But the biggest inconvenient is that he has a girlfriend right now and it breaks my heart. I really dont know what to do because we arent even close to start with since I have been living abroad for 3 years, so I was thinking that approaching him telling him that I would like to build a stronger bond and relationship with him to start with, and if one day he's single again see if it leads to something... But I am extremely shy to approach anyone, even if it's for friendship. I am terrified I will say something awkward and this will tear us apart even more.
