Father of my child not even acknowledging pregnancy now. Rant.

The father of my child is making it so clear that he wants nothing to do with the pregnancy. On Christmas eve he came to my job with his friend. I think it was planned because one of my coworker's still talks to him and when he came that coworker kept telling me that he's here. The father and his friend came in and he stared at me. He wanted me to take his order because he stood in my line and stared at me behind this lady but my other coworker was a lifesaver and insisted on taking his order. I think he was trying to intimidate me. They stayed and ate in the restaurant for 30 minutes and NOT ONCE did he ask me about the baby or my next appt. This dude could stare in my face and not even mention little baby. Here's a little background- He was very abusive emotionally. He broke up with me early in the pregnancy, wanted to get back together, and I refused. I was not about to go through this break up when he wants and make up when he wants cycle. When I refused, that is when hell broke loose. He texted my phone with crazy things, so I blocked him. He was nothing but drama. My last appt he knew the time and date, but did not show up. Instead he called a mutual friend and asked her if I went to the doctor!!! And then he blamed me for him not showing up to the clinic which is 5 mins from his house. He relishes in drama. But, the fact that he can look me in my face, see my little rounded belly, and not say anything about the baby is appalling to me. I have no more excuses for him because he can look at me and not even acknowledge baby. It makes me feel like he has completely wiped his hands of the pregnancy and the baby.
