My husband is an asshole

So, when I had my baby back in April last year I found my hubby texting a girl from DR(we are Latinos). She was telling him how she broke up with her hubby and needed money and he said: don’t worry beautiful I got you(and offered her twice as to what she was asking for) we had a fight he said they were just friends so I let it go. Now this year back on March I found messages to the same girl, with a different name, she says: send me my valentines present, and he says: I sure will because you deserve it. I asked him: who do you need to send this person a Valentines? He said: who? What are you talking about? So big fight. After that I find pictures of another woman ask him about it he gets defensive we fight, he says it’s from a group that he has with some friends. So I said: ok, then, don’t delete them because I’m the details of the pictures it’s going to say who sent them. Hess what?! He erased them faster. Today I check and find more pics of a girl, but no conversation, his pics automatically save on his phone, so it doesn’t matter if he erases the convo, it stays there. I want to get a divorce, am I overreacting?
