I’m not sure what to do

So I’m pregnant. The father of this child is not the person that I want to be with or even should be with. I know what I’m doing about the baby someone else is getting blessed with it but I’m not sure what to do about the person I love most in the world technically I cheated on him and I thought he would be better off without me but I still love him and would give anything In the world to be with him.
