I just recently found out that I might be technically cheating on my boyfriend okay so what's going on is that I didn't know that we were still dating and I guess my boyfriend thought that we were still dating after going with half a year without contact or even talking to me it was technically longer but I don't remember how long so am I in the wrong? I mean like the only thing I did that could be considered cheating was kiss this really cool girl and then it was like a dare and she was also lesbian
