Caught my bf txting other women

Last week my bf left his phone. I decided to check it because he has been distant n more attentive to his phone then me or our new born bby. Weeks before I caught him watching porn he confessed he did it to fight the urge of cheating since we had not been intimate, which to me sounds like bs. I whent back on his phone n he has been contacting this female since I was pregnant, the hoe is already married n still sends him xrated pictures she intends to meet up with him in person so I decided to call her n tell her about me n the bby n our relationship. I think she told him about it because he confront over a call who I called n said I called his customer I told him I knew the truth n he hung up. Now I dread him coming home n what's going to happen. I am alone with a newborn no job no money but this is not the life I want for my little one... Idk what to do or say I'm not good with confrontation.
