So confused...

So my fiance and I have been going back and forth on whether he wants another baby. Well I got a positive pregnancy test and the negative. After that he said he doesn't want any more but then last night he was talking to our son who is 2 years and 10 months old and says.... "I want more of you, I think your mommy can manage to make that happen by Christmas". Like wtf. Idk if I want to try anymore. It's like a never ending decision. Why can't he be all for it all the time? Sorry for the rant.
