Advice please!

Im only 15 and accidently got pregnant by a older boy when i first told him he always wanted me to get rid of it but i kept it. Now 6 months gone i found out hes had a girlfriend for 3 years and hes got other girls aswell. Im very upset and hes controlling he wont let me talk to anyone else and i dont really want him around my child until he acts like a man. Is that too mean?
