ok I don't normally post complaining rants because a positive attitude yields a positive life BUT I'm kinda freaking out right now....my SO and I haven't been on the best of terms but we have been together so long we are trying to make it work and he just told me he didn't care if the baby has his last name or mine....my daughter of course has mine bc she is not his and her father and I were not together and he is not involved at all but I figured with our history and the fact that he is an only child and this will be his first child and a son at that that he would want a namesake....?!?!?! maybe it's bc I'm 6 1/2 months pregnant and sick but I really am freaking out bc to me it sounds like he doesn't care bc he doesn't plan on being around much....??? irrational or what do you ladies think?
