Husbands Disrespectful!

This is going to be a little long sorry. My husband was in jail for 5 years I waited. Took care of everything while he was there even sending him 600-1000 a month so he wouldn't have to eat anything he didn't like kept money on the phone so he could call twice a day... He's been on parole for almost a year. Got off the other day now has a code on his phone,caught him talking to a girl from out of town and now everytime I say anything he's like I'm not changing if you don't like it leave me. I feel like he wants me to leave so he can say he didn't ruin our marriage I did... What should I do cause there's no physical cheating just basically tells girls from far away that he's single.
