Baby's last name?

Robyn • Alexander 8/4/2017 🧒🏼 baby #2 due August 👶🏼
Okay so I'm still in first trimester with my first baby and have been with my boyfriend for 11 months now and love him dearly and hope to marry someday but my issue is with the last name, my last name is Graham, but my baby's dads last name is Boner. I'm just scared in case the baby has a lifetime worth of bullying if I give the baby his last name, and to be honest I don't know if I want to take his last name either, I just don't know what to do, any suggestions?
