My husband wants me to get an abortion

I’m currently 10w 3D pregnant with baby #4. This was a complete surprise as we were done having babies and using protection.

He says we can’t afford another baby (we both work- me only part time so we don’t have to pay for daycare). Yes another baby may make us live a little tighter but it’s doable.

He also says we don’t have room for another baby (we own our 4 bedroom house). We would loose our guest room but so many people don’t have guest rooms so is it a huge deal??

He’s not the most attentive parent and I think he’s just coming up with excuses so he doesn’t have to watch another baby while I go to work (I only am gone for 3-4 hours Monday, Tuesday, Thursday and Friday) I work from home a decent amount. He likes to lay on the couch and watch TV on his days off instead of helping me out at all. I know all this and am still willing to take on another baby even though I know I’m going to be doing it basically by myself.

Any advice on what I can say to him? I’d like to convince him to keep this child because I don’t want to just keep it and him resent me or we start having marriage issues.

Sorry this is so long. Thanks for any advice in advance
