AIO wife(30f) in another country has spent two days in a row with her old friend(m), did not spend night with him of course

For context, I'm alone in U.S. watching our house and pets while wife is on a trip to U.K. to see her family for several months and it hasn't been easy on me. This dude in question supposedly married and my wife has known but not seen this person since they were very young, and they got coffee last week, that's it. Yesterday they went alone and saw a stage play in London, but not before him giving her a driving lesson in the morning (driving in UK is very different) and then getting drinks for a few hours before the play. He bought the drinks and the tickets. To me this felt like a date which I told her, and said to make sure his wife knows he's spending this money on you and that you aren't sending him the wrong messages. Today, she sprung on me that she was going into the city again to spend 5+ hours walking around and getting drinks. I admit to losing my temper but AIO?

Note: Explanation of stuff about cheating, when we first got together 7 years ago I didn't know our relationship was that serious (from signals she gave me!) and visited a fwb of mine. Not long after that she revenge cheated on me, but we were very young and have been happy since then. However, just last year we almost divorced over her infidelity where she started seeing someone else behind my back.
