Help :(

Been with my boyfriend for nearly a year and a half and i am currently pregnant with his baby. Only found out yesterday so im not there far. Im in 2 minds about whether to keep the baby or not. I already have a child from a previous relationship. Me and my partner argue sometimes, yesterday he got drunk and started on me because he had too much to drink and the police was called. I just dont know if its the right thing to do to bring a baby into this
