Totally confused

I am 8 weeks pregnant. My partner and I have been together for 5 years. 3 years ago, I had an abortion (his child) it was a hard decision but was the best for us at the time. The last 3 years have been, at times, rocky. Since my abortion 3 years ago, I’ve had a desire to be pregnant and have a baby. For 3 years, my partner has been reluctant but we began having unprotected sex and I became pregnant, again, very quickly. I’m now 8 weeks along and am regretting wanting this reality for myself. At first, my partner appeared happy and excited, however, he is now stating we will never work. He hasn’t asked me how I’m feeling or anything related to this pregnancy. I’m now thinking of having another abortion. This is the saddest and toughest decision...I never imagined this would be the outcome of becoming pregnant again. I’m so confused and unsure if I should abort or have the baby and be a single mother. Im scared to do this alone but I know the devastation of an abortion.
