I cannot handle my babies dad anymore he seems so heartless and selfish lately and yesterday was our first prenatal appointment the first time ever seeing our baby and the first thing he did was start a HUGE fight with my mom outside the office as soon as we walked out. I don't know what to do and I'm so heartbroken right now😭😭😭😞😞😞
