can someone please give me advice

so i recently found out i was pregnant by someone who i just mess around w on weekends, he wants me to abort the baby because hes going to jail and wont see his child be born or be there for the first year or 2. but november of 2019 i lost my son at 18 weeks so aborting this baby isnt the easiest. idk what to do and i feel selfish for wanting to keep my baby. can someone please give me advice
