Did he technically cheat on me with his baby momma?

My boyfriend (24M) and I (24F) have been dating almost a year, about half way through he found out he has a daughter with a women in Italy that he had dated when he was in the military before we got together. He had told me he rarely had contact with her and when he did it was only about his daughter and he was going to go hopefully this winter to get a DNA test. I got a random suspicion the other day and went through his phone while he was sleeping, which was a big break of trust to him. But I found their text where he called her the names he called me and said he loved her. When I confronted him he said he had to do it and that otherwise she was threatening to not let him see his daughter and showed me where she said he had to be there to see her by her 1st birthday or he’ll never get to see her etc. he also told me that she did know about me, he doesn’t love her and he loves me. I believe him when he said he does this for his daughter but I think he really loves her, before the last three days when he started texting her he would go weeks without speaking to her he said. He says he only wants me but I don’t know anymore, I told him he wasn’t allowed to say that he loves her or call her the names he calls me and he agreed and also said if I went through his phone again he’d be done but said I can ask and he will let me. Im not sure what to do in this case, I don’t want to break up because I love him but I think he really loves her.
