I’m pregnant but my boyfriend wants to get rid

A little bit of background, so me and my boyfriend started out as an affair, and have since been divorced, we’ve been living together a year now, however this is the second time I’ve caught pregnant whilst on the pill. The first pregnancy he forced me to get an abortion, however I really don’t want to go through that again, I really want to keep this baby. He’s a lot older than me so I understand where he’s coming from he’s 56 and I’m 23. What do I do, do I keep it a secret until over 24 weeks if possible or do I tell him. I love him so much but not sure where to go about this.
