Is there anything else I can do or is that it?

soooo...ive been friends with this guy josh since last year. and weve always been close. anyways, this year i ended up falling for him..i fell hard, trust me! and i still like him to this very second. he has a gf. i get that hes taken and everything. im just making sure to stay in his life. i call him and when i see him, he always hugs me. but, we cant hang out cuz hes always with his gf at lunch and stuff. he knows that i used to like him...and i still THINK he knows about me liking him now but idk for sure. i told him the second he breaks up with her, he would tell me first. and we pinkie sweared on it. then, i said we would go and talk **** about her together. lol so i pretty much got dibs on him after they break up. is that all i can do for right now?
