Awkward

I need to tell my friend with benefits that I am pregnant but I don't know how to go about doing that. Do I do it over text? Tell him we need to talk and sort out plans to see him? Or just make plans to see him and then tell him? I'm only 19, so this is a weird situation for me. I'm keeping the baby I just don't know how to go about telling him. I'm mostly scared he will push abortion or not want to be the child's life. If he chooses to walk out that's his decision and I can't prevent that, even so I will raise my child alone if need be.
