I'm so devastated

I'm 14 years older than my 20 yr old boyfriend. He doesn't have any kids and I have 4. He recently moved in. Im now 6weeks pregnant. I just had a miscarriage 2 months ago. He is more so forcing me to have an abortion. I don't believe in abortions. I was an emotional wreck when I had my miscarriage and didn't know i was pregnant. Right now is the worse time to have a baby. I don't know what to do. He's been so mean to me since I told him I can't bring myself to have an abortion. I love him so much but if I have an abortion going to hate him for life. If I have this baby he's going to hate me. Im so lost right now.
