I think she been cheating?

My girlfriend claims to have been raped when she was young and she been stalking the guy on insta ever since. That’s before we met. Recently she wanted to go to meet him as he has messaged her. I didn’t say much so she went out with him for a coffee. After that they been texting each other here and there but one day I lost it and made her tell him not to call her again and she blocked him. Before that we had arguments and she blocked him and I unblocked him and she didn’t block him. Yesterday she tells me don’t be mad but I didn’t go for a coffee only but we went out for McDonald’s another day. Now I feel very betrayed what shall I do?
