Should I feel bad?

This guy has been texting me and I think he might like me because of how he talks to me but he kinda just pressures me to talk to him. So I'm new to the school and he was my only friend, well was. But he would say "imy" or "answerrrrrr" and it would make me uncomfortable because I felt pressured and my boyfriend saw everything. So my boyfriend told him to calm down because I was busy sometimes and he was just always questioning why I wasn't responding to him, but now I feel bad and I'm nervous because he was my only friend but I mean I didn't feel comfortable and I didn't want my boyfriend to get suspicious over nothing, should I feel bad?
