Is it normal to feel afraid about him not accepting his son?

To keep this story short I'll start off by saying I am having a baby by my ex boyfriend who isn't quite happy about it and I don't know how to cope with it. About 3 years ago we dated for almost a year and we were inseperable. We were a serious couple, I was the first to meet his family and vice versa. When we broke up, we tried getting back together numerous of times but it just didn't work. We argued way too much and I might be the blame for that most of the time. One day we had a bad argument and after that we stopped talking until recently.
This time it was different, he told me he was talking to someone new but it was on and off.. nothing serious. We began to hang out but it was always with his family. I've always cared for him so whenever he needed a friend, I was there or someone to pick him up, I was there. He was leaving to the army soon so I came around more often... and sometimes we did the unthinkable. In may I found out that I missed my period but I've missed it before so it wasn't a big deal to me. I had started taking a swim class, two months gone by and I realized I still didn't get it. I told him about it but in the state of denial we both said it might have been because of swim.
I took pregnancy test and they came back positive, I showed it to him and he told me to take another test at a clinic. I said I would make an appointment when I can. We began to talk about our options and we decided abortion would be our best bet because in his case "we argued too much", though he is against it. In the end he said it was my decision but he wanted to know what I wanted to do before he leaves for boot camp, I told him I'll do what he wanted which was the abortion. I made the appointment for the termination but when I got there I told myself I can't do it, I don't think I could live with that guilt and at that time I had already felt an emotional bond with my fetus.. I couldn't hurt it. I was 19 weeks.
He already left for boot camp and by the time I came to my decision at that clinic he was already about to graduate. I had to write him and let him know that I kept the baby and hope he gets it on time. A few weeks gone by and I havent heard from him. I decided to talk to his sister when I found out his parents flew out to his ceremony. I told her I was pregnant with his baby and she congratulated me with tears of joy. She then later told her mom who was on the plane back home and told me not to worry to come back tomorrow so we can talk.
I came the next day and we talked. His whole family happened to be there and they said to me they were disappointed in him for telling me to get the bortion because he had just been baptized but they were happy it was me who was pregnant rather than the girl he had been seeing. They talked to him on the phone the next day and he was furious.. he said he never got the letter and was afraid of getting kicked out of the army. He also said he wanted a paternity test -_- when I talked to him which was a couple days later he was still angry saying I ruined his life.. with that being said I'm afraid he's not going to accept our son. His family told me not to worry about him because they don't want me to be sad.
It hurts coming from the man that once loved and cared about me. I do love him but I can't talk to him when he has nothing nice to say. I don't want to be with him and I know he doesn't want to be with me. Im happy I'm having a baby by someone I knew for over a year who still means a lot to me. His family is also very happy asking me to move in with them.. I just wish he felt the same or is atleast supportive. I need to do whats best for my son and I want him to know that we love him equally. What do I do world.. what can i say to his father.
