what should I do??

basically I'm in a long distance with this guy in Brazil, and they day he asked me to date him was the day my fuck buddy asked me to date him too ... we've only fucked a few times but like he's amazing at sexy and he's kinda awkwardly cute but idk when I'm with him he doesn't really treat me like his girlfriend, like he'lol kiss me here and there and sometimes hold my hand but most of the time he only shows his affection towards me when we're in the bedroom fucking. the guy in Brazil has no clue about this and I feel so bad about it because I'm an honest person and it's killing me that I'm not being completely honest with him and he treats me amazing and sends me so many cute messages and he's already spoke to his family about me!!😁😁like I love him but I like the guy I'm fucking... what do I do girls???😩😩
