Happy family gone

Today I broke up with my son's father. We have been together for what would have been 4yrs September 26th. We have a one yr old son together. I broke up with him because he can't keep a job. He works for a few weeks and then won't work for months. He has not got our son diapers or wipes or anything in months. It if wasn't for my parents and my son's other grandpa I would not have been able to get him what my son needs. I'm so heartbroken. I always thought I would have a happy family with our son, his dad and I but sadly that can't happen.
