i have a crush and i have a boyfriend

so i have a boyfriend 19 and i’m 17 and we’ve been together almost 2 years. the beginning of our relationship was rocky because of both of our own mistakes but it grew into something beautiful where everything is perfect and we only grew stronger. he is perfect for me and is the best boyfriend i could ever ask for. and ofc i love him more than anything. but recently there has been someone new at my job and for some reason i can’t help but be nervous around him and super anxious around him and obv i find him very attractive. but i don’t act on it by flirting or anything i just stay cordial because ofc i love my boyfriend and nothing is worth losing him. i tried to like ignore it but honestly it’s not going away. but i do feel terrible for feeling this way about him while being with my boyfriend even though i try to ignore it. am i a bad girlfriend?
