I have been casually seeing someone i work with, for 3 and a bit months, very casual (more casual on his part - I would have taken it further) today another colleague and i were chatting and she mentioned that he has sent her a sort of flirty email or two..she said it was jokey but saucy! she doesnt know we have been seeing each other.. so i told him i knew and he said it was nothing was just a joke, but he apologised and said he wouldnt do it again as it meant nothing and he wants me.. seeing as we are casually dating only and not open about it at work does this seem ok? or is he a fuckwit lying bastard? the way we started seeing each other was that he emailed me with some flirty emails by the way. he has text me tonight to say he loves me! what do i do?
