I wanna know if I did the right thing.

So this man I have been talking to for a year from a distant place. He is very nice and talks to me everyday and video calls with me. We have a mutual understanding that we will only be in a relationship after we meet in person and it’s already scheduled and he already bought a ticket. We have shared a lot of things to each other and even send cards to each other’s address. It feels like a romantic relationship already although he refuses to put a label yet. But recently, he told me that he is gonna spend an entire weekend with a friend who is a girl whom she met at the same platform that we did. And he really did even though I acted cold. And he didn’t noticed I was upset and he even sounded very excited. He said that she is not her type and he don’t like her after some time of talking because she was annoying. He ensured me that it’s only friendly. But it bothers me a lot because it just don’t feel right and that a man and a woman spending a weekend together. Who is he fooling? So I decided to end it. But now it gives me second thought wether O was just overacting and they are really just friends and he just want to show her his place?
