Surname

So my partner and I are on and off. Always have been. We don't live together. I was supposed to move in together when I fell pregnant but when I did he  decided he didn't want me to. We live 100 miles apart. 
He has basically gone mad because I said the baby would have my surname as we were broken up but we are now trying. I said I'd double barrel it and said it would be his surname and then mine Gladish - Love 
He's also gone mad about this and says he wants Love - Gladish
Thoughts??
