Idk what's going on with my bf I haven't seen or heard from him since Monday when I left for work and honestly I don't care any more..... He refuses to do anything that I need/ask him to do.... he doesn't work, all he does is play his stupid video games, smoke, and drinks... at this point I'm prepared to take care of my son by myself.
