Is it normal to not know how to feel?

Yesterday I found out that i'm pregnant, for my lame ass cheating, disrepectful boyfriend. So I don't know what to feel, one moment am happy, next minute I remember how unreliable this bastard is. I told him about it and he was cool, we were just thinking how it's possible cz I used the pills, he has no doubts about it since we literally spend everyday together(even if we just fighting about something). He actually laughed it off cz at some point he made a joke after sex that we would have our first born next year June. Personally I don't want to hear the word abortion, I already feel over protective of my baby even though it's just cells. I hope this fucker don't suggest it cz he asked me what do we do now, I told him am shocked and can't think straight at the time. He comes from a very wealthy family, they own businesses and appartments, so I don't want to hear the money excuse. Am 23,he's 25 both college graduates. Am not suggesting to move in together, I don't even know whats best for me right now , I just know I wont kill my baby that's all am certain of. Has anyone been through this? I seriously don't know how to feel, am kinda happy and sad iin?
