kinda disappointed

i created a fake snapchat account for a girl named hannah and she had blonde hair and blue eyes and i added my boyfriend to see if he would add back a girl he didnt know and he did. and he sent a picture of his face right off. i sent a couple black screens and he kept answering right off. and he even told one of his friends about it bc he added “hannah”s account too. what the hell am i supposed to think? if i did that to a guy he would be really mad. i dont wanna ask him about it or tell him what i did bc im scared hes gonna be mad but i just dont understand why he would do that. especially since he checks quite often who i talk to and he tells me to stay away from a lot of his friends that are guys. i feel like he controls me but i cant even do anything, and if i told him about this to prove my point, he would be really mad. idk what to do. :(
