He still likes her?

My boyfriend used to like this girl from 2017 to September 2019, which was when we caught feelings for each other, throughout our relationship he has continually talked with her and hung out with her in person we are a long distant relationship but she’s in person and he can hangout with her. She told him she liked him before we started dating and he turned her down. I know his ideal body and she has it and I’m no where near what her body is. He still takes care of her and they text a lot. I don’t want to sound like one of those crazy jealous girlfriends and I feel bad for even feeling jealous because I don’t want to stoop there but I feel like he’s just using me to pass time
