A bit of background: I have a 4-month-old little girl and I've been with her mother for about 5 years.  
  
It feels like my gf hates me. It feels like my baby doesn't want anything to do with my anymore. Things used to be fine... My gf used to be calm when I acted out. My baby used to love when I held her. Now, my gf gets angry back and we fight... Now, my baby cries when I hold her... I don't know what went wrong. I don't know why my gf acts this way now. I feel alone... The only two things that kept me going seem to be slipping away. What do I do...?
