having your ex/bd to be there at birth!!

just looking for some advice, I'm in two minds wither to have my baby's dad my ex at the birth of our child? I don't feel comfortable with him being in the room with me, am I wrong in not wanting him there? Should I let him? I don't want to not let him come incase I regret doing so afterwards but I really just don't think he deserves to be there in the room experiencing it after not bothering with the pregnancy or baby for months.

!! just clarifying I didn't say I would stop him meeting his child !!
