I need advice

I’m really going through it right now and I don’t know what to do. My fiancé has had a baby on me and I thought that I could accept it. The baby is two months now and today he got to see here like bring her to the house. All I could feel was hate and anger I know it’s not the baby’s fault she’s just a reminder and not a good reminder. I told my fiancé I don’t feel comfortable around her yet I’m just not emotionally there am I wrong? He thinks that because I love him that I should love her truth is not really sure if I love him anymore the cheating and the baby has put a huge toll on us more so me.
