Should I be done?

I feel like if I’m asking this then the answer is pretty much self explanatory but I’ve decided to come here to get some other opinions. My fiancé and I have been together for 2 years, we have a 6 month old daughter together. When we first got together we moved pretty fast, we moved in together after about 2 months of dating. When we first moved in together I went through his phone because he was being sketchy with it and found naked pictures of girls on his phone. He said that he had them on his computer and forgot about them and then they synced to his cellphone. I forgave him but never forgot about it (obviously). So we just moved across the country to be closer to my dad since my mom passed while I was pregnant. He left his family back in our previous state. I was staying with my dad while he was finishing up our house because it was still being updated. He was about 3 hours away from my daughter and me for about a month and a half. I had been looking at his Facebook and this random girl was liking all of his shit so I added her as a friend and she declined my friend request. I messaged her because, duh, super fucking sketch. Come to find out he had been messaging her. Granted, it wasn’t really anything bad but he was definitely being overly “friendly”. I asked him about it and presented him with the screenshots she had sent me and he admitted to talking to her and deleting the conversations. I was pissed but I mean im not going to breakup our family over that. We moved into our house last week and since then he’s been really distant lately and he’s normally really clingy. So I went through his phone yet ANOTHER naked picture of some girl in his “Recently Deleted” folder from Feb. 12th, before my daughter and I were up here. He says that it’s some Instagram girl, it was just a pic she posted and he took a screenshot and that he was messing with his buddy on Snapchat by sending it to him and pretending that it was the girl and she wanted to hook up with his buddy. (Sounds like a lie, I know) so he messaged his friend to confirm who says nothing, just sends “🤣” that emoji. I kicked him out after he told me that I was insecure and that I was a “fucking piece of shit” for not believing him. SOO he left, he doesn’t have a car because we only have MY car, we live in RURAL Alabama like 30 mins away from the nearest grocery store rural, so I know he’ll come back sooner or later and want to talk. I’m 24, no job yet here (I have my degree, and have been looking just no luck yet), my house is paid for by ME so I don’t have to worry about that, but I don’t know if I should try to work it out AGAIN, forgive and forget ONE MORE time for the sake of our daughter? Any advice?
