To keep it short and sweet a plate I had been seeing for 2 years had on numerous occasions brought up commitment which I shut down promptly every time... except when I didn’t.

Perhaps a bit of Oneitis had set in given I had become so comfortable with her after seeing her for so long, however going against my best judgement I caved and agreed to be ‘exclusive’ with her.

I can honestly say that I never expected her not to continue to fuck other guys given I told her this still doesn’t make her my ‘girlfriend’ but she assured me she only wanted me.

Last night she left her phone unlocked near me with her messages open and yes I saw a guys name so I clicked on the conversation. A 5 second glance showed her asking if he wanted to meet up again to have sex etc.

She has no idea I know, and I’m not angry or disappointed or anything however I would like to know the best way of going about this in order to not lose her as a plate because the sex is fantastic. I’d like to bring it up purely because I don’t want to have to watch her continuously lie to my face when I know better, but how do I go about it without spiking her ASD and having her walk away completely?
