what should i do?

im 5 months pregnant, my boyfriend broke up with me the other day because i was being moody & hormonal after i found out be was smoking with another female. he also insists i should get an abortion & he leave him alone for good. this is all new to me because this is my first pregnancy & i didnt expect my boyfriend to just up & leave me hanging. its been like 5 days since ive seen him & everytime i call him he rejects my call & blocks my number.. any advice ?💔💔
