I know the title sounds bad.. I am in a relationship and have been for two years and living together.
Over the last 8 months their has been this guy at work and i get the feeling he is interested in me. We speak and say hello every day etc at the start he used to seem very nervous around me he would stammer when we had conversations and if we bumped into each other unexpectadley he would go all red and flushed. He always gives me this stare when he walks past which is quite sexy and makes me think he is attractive when he does this! he doesnt seem to treat any other women at work like this and doesnt seem to notice women as much as he notices me. I was collecting for charity and people at work were giving say £4 each he put £15! It has been going on for some months now and i feel their is A LOT of sexual tension between us. When my partner meets me from work the guy seems to get jelous and moody with me the next day which makes me feel kind of strange as i cant tell what he feels. He makes comments to colleagues in front of me like 'i am so tired i need to get a bed in my office and tell the wife im working late to get some sleep' it all just feels very strange i cant work him out! Am i imagining things or does this guy like me. I am starting to develop feelings for him because of how he makes me feel. I would never go their obviously but all the tension is bugging me and i hate that i dont know what he is thinking! He is married and has been for over 10 years with two children and seems happy with that he always speaks happily about them. I am 24 and he is 32.
I know it is probably just harmless flirting that is making him feel good but its been going on for ages and just wont stop i really do not want to develop strong feelings for him but i cant seem to help it cause of how he is with me.
What should i do?
