Im not sure what I should do. :( The baby daddy hasn't contacted me for weeks. People say to just forget him. But how do you forget someone who got you pregnant. The last time we spoke he asked if I was sleeping with someone else. The last thing I am thinking about is being with another man. I barely have the energy to eat or even get out of bed half the time.
