I often chat to a guy in another department at work when we were office based, just a chat here and there, we linked up on Fb and chatted now and again on messenger. Now he is messaging me daily and even said he saw me come to the office the other day (I had to collect something, didnt know he was there) and said have I done my hair as i looked amazing.....next he is asking me to meet him early one morning so we can walk alone in a woodland area he knows and really enjoy each others company. I politely said that sounds nice and he said ' I want to go tomorrow now' so I made excuses.
He is married with kids too and what seemed a friendship with a work colleage now feels a bit weird. He wanted me to message him the other morning when he woke up as needs his fix of me.
Should I back away?
