How I know if he loves me?

OK,so ima surprise my boyfriend and FINALY meet him, ima do it with a group then ima go alone wit him and see if he a good guy,but I THINk I’m in love wit him and im not sure if he really likes me or if he just playing a joke on me :l I hope not. I’ve told him about me and we talk a lot but…we have different religions and mine is..a really rare one. And well what if he doesn’t like me?what if he thinks im too young?if he does love me 2, how can we stay boyfriend and girlfriend when we are states away from each other?. So now im just not sure if he really like me. He told me he loved me first but it could be a lie…I dont want 2 get hurt in anyway,but im so sure he will like me. he is my best friend and he helpd me get through a rough time , and im so happy that he did but then we started to talk more and more than he just said “I love you” when we were talking..so I was like “what really?” and he was like “yes,I do” so I said “I love you 2”. but now we want 2 meet and im going to meet him, but how do I know if he really loves me,without me meeting him?
