Opinions about delivery

Hi all, so this is just kind of a question looking for opinions. My ex and I found out I was pregnant a week before our wedding.... Well the morning of our wedding he left and gave no reason. When I got back to town I had my first visit and ultrasound, begged him to come... He didn't. Apparently he didn't believe I was even pregnant til about 3 weeks later with another ultrasound with my name on it. Anyways, he pretends to be daddy on Instagram and Facebook but won't act like a daddy when it comes to the pregnancy, etc. so my question is (I don't want him in the delivery room) who would you take in there with you if you were in my shoes... The ex, or someone else. TIA. :)
