Baby name drama!!!

So I am not yet pregnant. But my SO and I have a list of names we like for when I do finally get pregnant. I was going over the names with my mom and best friend at lunch one day, and they both decided to chime in about which names they did not like. And of course the ones they don't like are mine and my boyfriends favorites. I'm irritated that the 2 most important women in my life couldn't keep their mouths shut and feel like it's ok to talk about disliking names that obviously I do like. They've got me feeling like we should pick new names. I won't cave but God I hate it. They have since asked if we've thought of any other names... how do I handle this? Especially since I'm not even pregnant yet.
