@rhubarb39 I hope lunch is a long one and takes your mind off him. It is so hard.
@Jonsnowsghost it's horrible I know, I hope your day has got better 
@Notcoolmum that's a curious one...he was a casual relationship where you both got much more involved and fell in love I think? Did he go back to his ex? Sorry if I've got confused. I think if hes confiding in you and wanting to chat then he definitely misses you, particularly on an emotional level. Hes clearly not getting what he needs from his life without you. Plus you know hes physically attracted to you. I am not sure what is best to do next...I guess he needs to know he might lose you if hes not trying to return and commit.
I've had a bit similar from mine. It's been a couple of months and hes living with his ex. I make no contact but he is in contact weekly with messages and it's clearly secret from her as if I reply then WhatsApp says sent but it doesnt deliver until he reactivates his account. He knows I have no interest in being the other woman. But I can only think he misses me and telling me about work and his family etc implies that he wants to keep an emotional connection to me, maybe their relationship isnt what he hoped, who knows. I suppose it's hard to walk away from someone who loves you.
@TinselAndKnickers Good track, Pink 'Who Knew' is great too
