Feeling like she doesn't wanna fix this ,

Idk what to do anymore. I have a pregnant girlfriend who's almost due. I'm on active parole. And I fucking, relapsed... All she does is pick fights and then leaves .. or she always trying to break up with me.. something is going on I just know it. I asked her if she was cheating on me she said no.. it's like she fucking hates me all of a sudden .. I miss my babies so much idk what to do
