I have been with dp 7 years and we have 2 dcs, we are very much in love and happy. I started a new job last year and work very closely with a lovely man, some weeks we spend more time at work together than at home with our partners. We have gotten real close as friends, good friends and he really looked after me (our job is very physical) during my pregnancy. He is Much much older than me, he has kids roughly my age and there is absolutely no physical attraction or any other, yet i feel guilty for getting so close to him if that makes sense, i just need some perspective i think.
