I've developed an inappropriate obsession with a male work colleague and am not sure how to make it stop. For years we were just mates, then we spent some time working on a project together and he was very understanding whilst I was going through a stressful work situation. Seeing this new side to him, and the fact that I've been single for far too long, meant I slowly started to developed feelings for him (basically started to fancy the pants off him). However, he has a DP so i never said / did anything and probably actually give off negative vibes to hide my feelings.
After the feelings developed I became jealous of him working closely with other female colleagues, became overly nosey about his life, and starting following his movements on social media very closely. This led to me feeling very guilty about the obsession and behaving quite weirdly around him. At the moment I'm keeping my distance from him but I am still obsessed with where he is, what he's doing etc. I've even attempted to log into his work email account to find out why he's on annual leave.
This all makes me sound like a hormonal schoolgirl but in fact I'm in my late 30s. I know that no contact would be the ideal way to go but I see him at work virtually every day, and every time I see him it sets off the god i really like you feelings again. I'm dabbling with OD, but no dates yet, to try and take my mind off it.
Any other suggestions, or just some harsh words about how stupid I'm being, would be useful.
