Am I being selfish?

I broke up with my boyfriend after a daycause he got to clingy and perverted. I felt kind of insecure and bad. Especially since after I broke up with him he asked out my bestfriend. ANd since she didn't know we dated she agreed I didn't care much but I was hurt. I started to talk to this guy that goes to my school and gradually fell in love but. He and my other best friend met and she said she liked/hated him. Which usually ment she loved someone. I kept stating the fact I'm in love with him cause I said that before she met him. SHe asked for his sn and i was hesitant to give it to her but I still did. I'm feeling selfish cause I tried to not give any background about him when she asked. I love him but I have a feeling my bestfriend does, i told her I love him before they met but will her love for him prolong. IS there a way I can straigten it out and say I don't like them being too~ friendly ?
