Ill keep it short, let me know if you want more details. Currently in New Zealand with my girlfriend, traveling for a year. Before we got together she told me about a guy that she wanted to bang, and she would have except he had a girlfriend at the time and she didnt let it happen. This guy is in australia. Before we left australia and came to new zealand, before we were official, she wanted to visit him again. But I told her I wouldnt stick around if she went to visit him for three weeks, so she decided not to visit him and came straight with me to new zealand. They texted a bit here and there, he was flirty with her and even invited her to bali, but she shut him down and said “my boyfriend would not like that or else I would.”

They had not spoken for a few months and now he texted her out of the blue and told her that he is coming to new zealand. She is excited to see him. I know for a fact they never banged but this feels disloyal to me. She is excited to see him, he is coming here to visit her. Should I jump ship?
