I left my sons father because he chose his friend & drugs over me & his son. Ever since he let his friend move in knowing i wasnt okay or comfortable with it there was tension, He wasnt working, smoking again & doing other drugs, told me he didnt give a shit if he lost me or his son. How do you choose your friend, drugs, & video games over your fiancée & child? How can you let someone tear your family apart & not give a damn? He let me walk away when i gave him the chance to better himself. He told me he didnt love me anymore & that was it. I knew i had to get out. So today is the day this mama is going to get all her belongings out of there to start over.
