Backstory is me and my ex partner have a 2 year old, our DD has his surname.
In October after a long talk we decided to give a relationship a go after becoming closer during lockdown (he moved in with us so that he could see our daughter without breaking rules as he lives in another country)
I'm on the implant but fell pregnant and as soon as i found out he left the next morning and I havent heard a word from him since November, his family say he wants nothing to do with us anymore and he's engaged to another woman. It seems very serious between them so I'm not sure that he will contact me again
Now I'm due in a few months and thinking about surnames, would it be strange to give my 2nd child my name although he shares the same father as his sister? Should i give my 2nd child his fathers name although he doesnt want anything to do with the child? Feel really stuck as I don't know what to do for the best.
YABU - His surname
YANBU - My surname
