Hun my bd hasnt been there for me at all. We dont get along. We broke up months ago. And im not giving my son his last name. . . .but unfortunately the dad can take it to court and get it changed. So just be aware of that.
It's definitely up to you hun. I just had my daughter almost 6 weeks ago and she doesn't have her dads or my last name she has my fathers last name. Before I had her we hadn't been together the entire pregnancy but ended up getting back together two days after she was born and now we're living together and talking about getting engaged. But I still gave her Melton as her last name not Claridge which is his or Mills which is mine. He was upset a little but he has no room to get mad because she doesn't even have my last name which was the point.
If he deserves to have his baby carry on his last name then yea u should but he has to b there for u throughout the whole pregnancy, show up to every drs appt , help buy baby things , even f hes not n a relationship with u he should still do his father duties while your carrying his baby...u kno wat I mean? The men or should I say boys that aren't there for their babymammas and dont care bout showing up to a dr appt but xpect to b there for the birth of the baby ,those are the ones that dont deserve to have they're baby carry on there last name !
Honestly thats all up to you, in yhe future if you ever decide to put him on child support there isn't no denying lol but like i said its whats going work for you.
