Boyfriend ignores me what would you do

I met this guy a few months back and the 1st month was great called texted came and seen me and my kids. We were both head over heals for each other. The second month he started backing off abd didn't really text or talk to me much. I decided that I was gonna confront him that texting 4 times a day was really not enough to keep interest in each other. We got in a huge fight abd broke up. We decided a week later to meet up. Well next day found out I'm pregnant with his child. He is still really distant. What is normal in a relationship to talk or text how often ect....
