Abortion, Yes or No??

I’m 22 years old, and I have a 13month old daughter. Today i just found out I’m pregnant 6 Weeks to be exact. I haven’t told my boyfriend yet and I know what he’s going to say. He wanted me to abort our little lady but I didn’t have the heart. I don’t think I’m ready to have another one as she won’t even be 2 when the baby is born but i think I’ll regret it and hate myself if I had an abortion :( any advice would be appreciated!! I’m just stuck 😩
