Am I am bad person?🤷🏽‍♀️🤦🏽‍♀️

Lately I have been texting my ex bff boyfriend we stop talking because she said I like him. But I am starting to like him more than just a friend and he tells me he has feelings for me but he does not want to hurt his girlfriend feelings. School is almost out and we are going to summer camp together and we are going to be around each other a lot I believe I am a bad person for having feelings for him. I need ADVICE ASAP
