I need some advice

I have gone through many hardships recently. I went through a surgery to remove my gallbladder after have the worst pain in life. I thought I was going to die. Two months after I lost my father. The day after his death I found out I am pregnant. I am not married and my boyfriend says he will be supportive, but actions do not match his words. He keeps saying that because I am 33 years I am a high risk and I might lose the baby. Sometimes I feel he wants that deep down. I try not to think about it and say to myself he must be nervous as well and will come around. But, he makes me feel terrible and sometimes I cry alone over it. No one knows about it as I have not confided in anyone about it. I don’t want my family or friends to hate him. We are both adults, he is 35 and I am 33, but since I have told him. He has changed drastically. Its been close to 1 month since I have shared and I have really seen him. We would usually see each other once a week and next frequently. I feel like he does not want me to bother him. I don’t know how much of it is my head and not. We are planning on moving in together by end of year. He had first said in 2 months and then changed it. I feel he is hoping my baby does not make it. But I love my baby I dont want that negativity to even been spoken said or thought about him. My family on the other hand have been super supportive. I just feel so scared and all the time. I feel like I have not been able to really be happy, because I need to be aware of everything for my baby to protect him. Some advice or prayer would be of great help. BTW they are twins but last week we could only see the heartbeat of one. The doctor scheduled me for another ultrasound today.
