Domestic abuse mums?

Pip • Pregnant with a little boy • c-section is booked for 4th July 2016 at 8am ✨
I'm just wondering if anyone has been in this situation. I'm deverstated. My partner has been physically and emotionally abusing me for over a year now, I've finally had him arrested tonight, they have him in custody and I've just got home from the station. However I've also just found out this morning I'm pregnant, with his child. 
Has anyone been in this situation and kept the baby and what was the pros and cons of that etc. 
I've got police and my friends telling me that this isn't a good idea and he'll have a hold over me forever now. But I've got a baby inside of me and I'm suppose to abort it because I'm a victim of abuse? I don't know what to think and I'm hurting so badly..
