My boyfriend wants an abortion? I don't

Okay I've been with my boyfriend for a long time we have a healthy relationship and are in love, but I'm having a lot a lot of pregnancy symptoms even though we weren't trying for one, and I can't test yet it's a little to early but he keeps saying I'm pregnant because I've had "morning sickness" at night and other very good signs of pregnancy I can't test for a couple days but anyway he keeps talking about an abortion and asking if he needs to pay for it and asking all these questions to be honest I don't want one IF I am pregnant but I feel like his family and him will be very angry with me because his brothers 25 and gets abortions with his fiancé his mom had like 4 and I know I'm gonna be judges for this but 7 years ago I had one I don't regret it because of why it happened an the person but I feel like I'd really regret it this time because of who I'm with and how happy I am but I don't want it to destroy something we both live that we have. I know I'm probably over thinking something that isn't for sure yet but I just need tips or if anyone else has been in this position.
