Search Results: how to catch a cheating boyfriend

Well he showed me the messages between him and this girl he just met in school. I felt a weird feeling from her so I asked if he could show me the messages. Well he did and although nothing showed he was flirting these lines sort of caught me off guard. This girl was totally fishing for compliments from my boyfriend which he never gave but she basically got him to follow her on Snapchat and she said how she would put him under some character there that she says he looks like and he replied with “I feel so special” then they were sending eachother memes and I think she said how great and funny the ones he was sending were and he replied with “thank you I’m blushing”. Nothing else in the messages showed he was flirting or trying to cheat besides her just bringing up her being “short” constantly and he only teased her about it like once or twice. They also had like a little back and forth banter about how she’s older than him and how he’s taller and so on. He’s cut off contact with her since then bc I told him I didn’t like this girl and how they were talking. He said he totally wasn’t trying to flirt with her and he didn’t think she was trying to flirt either he just thought she was nice and that he met a friend. Could he be lying about him not flirting?
