Dad does not want the babies

I am pregnant and me and the father decided in the beginning to not keep the baby. He doesn't think he is ready and I felt like the timing is bad. Our birth control failed us. I had to go to the ER about a week after I found out I was pregnant due to bleeding. They thought I was miscarring and they did an ultrasound and I found out I was having twins. when I seen my babies I couldn't bring myself to get rid of them. I have never had an abortion and I have kids from a previous marriage and I couldn't imagine life without them. So now he feels that I have betrayed him because I decided to keep them. I am very excited about them now and I love them more then ever. I think my hospital scare was a sign but idk. Am I selfish for wanting my babies now even tho I told him I would not keep it when we found out? I will be a single mother because I truly think this killed our relationship. Other than this our relationship was damn near perfect. I'm so hurt that he thinks of me as this horrible person because I did not have it in my heart to abort my babies. I'm just so confused
