I need advice but please read everything 🥺

So my fiancé and I have been through a lot. It all started back in September when we started fighting more than usual and i noticed that he’s been distant. I’ve had to beg him to call/text me more but he just told me he’s been “busy” at work which I thought was true at the moment so I let it slide. But I’ve had a feeling it was something more. So fast forward to December I went on his iPad and I saw messages between him and another female talking about very inappropriate things. So I called the girl and asked if they’ve ever met up and she said no that he didn’t even say he had a fiancé. So I confronted him about it and he said the reason why he did it was because we were fighting too much. So I thought about it and decided that I’ll just let it slide because I thought things would get better. So just yesterday I went on a game called summoners war where you can battle and talk to people online. I knew he played that a lot so when I was at work I made an account without telling him and I found saw that he was calling other girls “my love”, “cutie pie” and “adorable”. So I talked to him and he said that’s how he talks to friends. And I know that’s not true because when I’m with him when he’s on that game he doesn’t even talk to anyone. What should I do?! Should I give him another chance?? I need advice/help please!!!
