Hi, I'm really sorry to butt in, I see this threads a long one, I've read back some and got the gist of it.
Dior, please please please put ALL thoughts of G out of your head. It is so dangerous to be tempted and if you cross the line, you can never step back over it. Focus your energy on your dh. My, admittedly short, marriage broke up some months ago, for some time prior to this, I found myself responding to flirtations at work but like you, I didn't feel I was getting the tlc I really needed at home, but was told I was attractive, special etc etc by a couple of guys at work, and like a complete mug, I believed it when it was no more than bored married blokes testing the waters to see if they could still pull. It didn't go beyond mild flirting, texting and emailing and a couple of "I've always really liked you" conversations thank god, but I could very easily have got in out of my depth. Anyway, I split with dh; recognising I was happily responding to others flirting being a small but not insignificant reason.
I'm not very good at advice and tbh I've not read every single of your posts (under various names - how do you do that?!) but I understand 100% that it is nice to be made to feel attractive, sexy etc etc and to be on the look out for him, is he in the office, why hasn't he replied to my email etc etc but it is dangerous. Please please put G out of your mind completely. Also, say you did get it on with him, left your dh and started up with him, how much would you trust him? Not much, lets be honest. So recognise your attraction to him as you only being human and female and goddamn sexy but don't do anything other than window shop.
Again, sorry if I've missed any significant posts or I'm plonking my size 7s where they're not welcome, I just got concerned.
