Myself (M) and this guy , matched on tinder a few months ago and have been very flirty with each other but also having convos with a lot of depth to them. He's often typecast as someone who is insanely popular which he kinda is but it doesn't reflect when It comes to guys.

He lives about 2 hours away from me by train and I'd said if it was worth both of our time we'd visit each other. Things were going quite well and we both had people in our respective areas that were interested in us but they were people that were already established in our lives and we hadn't made any promises to each other to date or anything, we'd kinda just said we'd be FWB.

The entirety of the time we spoke , he was always good with responses , would prefusely apologise if he went some time without responding , was always eager to show me what he'd rehearsed. I think he was happy to have someone take an interest in a non sexual manner.

We'd made a habit of telling each other about meetups with guys, he has a lot more options around him due to his location. Previously he had mentioned he was going to a friends party and that a guy there was interested in getting with him and I didn't think much of it as it's normal when you're that popular to have people interested in you. He did end up getting with the guy and stayed over, he told me about it the next day but I did ask

All of sudden, like the flip of a switch, his energy completely changed. His responses became quite poor aswell as the quality of them. When I asked he said it was because of this guy from the party. What he hadn't mentioned up till that point is that he'd starting speaking to both of us at around the same time. My reaction wasn't really anger at all just disappointment that I was "the second choice". Am I wrong to have said to him that I was only interested in being friends with him after him saying this ? Or am I overreacting and making something out of nothing?

I made an analogy about if you knew someone wanted to kiss you at a club and you kissed someone else knowing that the other person was there waiting. Would you then kiss that person afterwards, Knowing that you were the second choice?
