I got pregnant by my son

So i am a 41 years old and was happily married with a husband and a son. He is 17 years old now. My husband was very good to me and i loved him more than anything. I do think i had a oedipus complex. One day, i was cleaning his room and i found a porn magazine. I browsed it and the things i saw disgusted me. So i confronted him about it but he denied it and said it wasn't his but i knew he was lying. I told my husband and he said we should let it go and it is normal for kids to watch porn. I was so mad at him that he didn't take my side. I yelled at him and he left. My son came to me and i told him i was sorry that i yelled at his father. He said it was ok and he left. I dont know what came over me but i went to his room and then we had sex. I feel so ashamed of myself. After a week, i found out i was pregnant and i knew it was my sons baby. So i divorced my husband and now we live together with my son. I dont know how i would be able to afford to raise my son and the baby but im afraid my son will hate me if i abort it.
