Marriage Problems

Here it goes. This is my last line of hope left. Few months ago, i found my first discovery of my husband screenshots of women barely dressed in a private file. I gave him a chance. My family told me that it is normal for guys to look at girls in that way. What hurt me most is if he looks at celebs it's fine but he looks at people who are his friends or girls he finds online. I feel really insecure. This thing keeps happening over and over again. I'm really hurt now. A week ago i saw two tinder notifications on his phone. I confronted him and he told me he was just doing that bcoz he got upset with me last night. But yesterday I saw on his google apps that he was searching for tinder yesterday. He even texted girls in a too friendly manner.Everytime i confronted him he will get really angry and now I just don't know how to handle this. I have a baby and currently pregnant. I really need your advice.
