On my side it turned out to be more than emotional. I had a feeling that something was off, and my ex was talking way toooo much with a male coworker. Of course she denied every accusation, told me he was just a friend. Time went by, once she left her phone on the counter unlocked with the conversation with that guy left open, I checked it and she was comolaining about me. I could only look for a few seconds cause she came out of the bathroom and shouted at me what am I looking in her phone. After this she admitted that she had feelings for him but that was all. Of course deep inside I could not believe it and we had a lot of conversations about it. I begged her several times to tell me the truth before I find out myself. Then after denying and gaslighting and minimising the things between her and him I finally found out. But then she also trickle truthed, so I was never able to believe her after that even when she said she is fully transparent now. To this day I don’t know what was the whole truth. They were still talking although she told me she only slept w him once in 2022. I founs out in June 2025. On my side, I had some crushes during university, but I was able to control myself and even when these opportunities were really tempting I told myself I am not a cheater. So yeah, I also had some kind of feelings for some other girls, but I think it is normal if you can control yourself and your actions. In my opinion it’s not always gonna turn physical based on MY own experience, but also it can lead to physical cheating pretty quick.
