I kissed a good friend AHH

So when I was with my ex he had this friend that we used to eat dinner with sometimes, then when we broke up I stayed in touch with him but my ex didn’t make the effort. Because of how I know this guy he’s always been out of bounds even though we stayed friends, then yesterday we went for lunch. We ended up talking for seven hours and didn’t even realise the time, then when we said goodbye he asked me if I was feeling something too....!!! Which I was and it was super super weird, we ended up kissing we both agreed it was weird, but then kissed again and said goodbye and it was the most bizarre but intense, exciting thing and I’m so confused...!!! We are at uni and now going home for the summer so unfortunately won’t see him for three months😭 this is so weird!!!
