Unexpected Pregnancy/Abortion

I got pregnant back in Dec & had miscarriage the next month. My SO & I had only eachother for a few short months, he was also just coming out of a relationship with a female he was still in love with. We were really together even though we didn't see eye to eye on a lot of things. Once i found out I was pregnant, I called him immediately to give him the news. What he told me was that we could NOT have this baby, & I knew it was because he still had feelings for this other girl. At that point I was broken because I had previously had an ectopic pregnancy & didn't believe i would be able to concieve afterwards. I do not believe in this, but Do you think it's right to abort a child,
If the pregnancy is unexpected?
