I need some advice im desperate

Im needing some advice. I have been back and forth in a toxic relationship. We had a baby on Aug. 2018. We split bc of cheating and i went back. Felt like if i would always have him against his will. I would constantly make excuses foe his behaviour. I lost myself "loving" him. Long story short. I was about to call it quits once and for all. Well i did but i took a PT and it came back positive😞 He basically told me he doesnt care about it and that he is getting his stuff out the apartment today. Im lost, broken. Idk what to do. I feel so desperate. I cant afford to terminate. 😞 and knowing me adoption is not an option
