Me and a colleague have been talking to each other for months now everyday for sometimes up to an hour or more even if we have been working from home. We are both married. We talk about work but mostly personal stuff about our lives, not our respective spouses, and laugh alot. Think we are defo attracted to each other as there are looks when we are in the office and lots of accidental touches. So I've realised a line has probably been crossed. I'm unhappy in my marriage which is no excuse. Anyway, he is leaving for a better job, his last day in the office isn't his last working day but I'm not sure if I should go in, it's our last day in person together and think things are escalating abit with the looks and flirting etc so not sure if it appropriate for me to see him in person again. I have valued our connection and speak to him more then I speak to anyone else, so wonder if I will regret not seeing him in person again. But think it's best to cut all contact with him incase things get more physical (I find him very attractive but we are both married). He called a few times today but I missed his calls then messages him to say I'm busy. Saddened by it all and bit confused.
