I don't post much but always enjoy reading the frank responses on MN. I have been thinking about asking this for weeks - but even putting it in writing makes me cringe. I have a good relationship with DH - married 20 years but got married young. I have never cheated on him except one drunken snog about 15 years ago. have been told people see us as 'the perfect couple (I know - dangerous as well as nauseating). So all fine. Except I have the most incredible crush/obsession with guy at work. Dream about him, fantasise, have to avoid doing any socialising as I am convinced I would sleep with him if given the chance. why???? Why would this even be a thing? I am not unhappy, have very fulfilling and busy life. I don't get it. Don't particularly want it to stop as at the moment - not hurting anyone and giving me a lovely glow. Can imagine if ever it became real - nightmare. Has this happened to anyone else and why do you think it does? First world problems - not enough drama keeping alive so we make shit up to rock the boat???
