I have been married for many years. TBH I don't think my wife has ever really loved me. She says "I love you" to family, the kids, pets etc. but never to me. If I ask her, she will say "sometimes". I think mainly it is gratitude that I "saved her" from a bad home situation. When we got married people were surprised and said "We thought you were more like brother and sister". She never really wants sex - maybe a couple of times a year, when we are out of the home situation, but she puts up with it, once or twice a week without any enthusiasm. She said once " I haven't felt anything for you for a long time". She says things like this from time to time. These things she says haunt me and I lie awake thinking about them. She confessed to an affair years ago and said is was purely "physical" and I forgave her. She said "if you want to get your own back, that's OK so long as you don't tell me". The opportunity has come up several times but I have always pulled back from the brink. Once she suspected I was having an affair and really pulled out the stops to keep me. New clothes new hairdo, sex every night.
So there is this woman at work. She works in another office. I met her some years ago on a training course and we hit it off straight away. The attraction was there but we were both married so just left it. I have met her a few times since and the magnetism was still there for both of us. We met up again at a works "do" the other night, we were (discretely) in one another's arms late into the early hours and had hours of deep meaningful conversation. I could feel myself falling in love for the first time in years. I had forgotten how it felt. At the end of the night she sat silently thinking for at least 10 minutes about whether we should go to bed. She is a widow now and single. In the end she said "I have an early start in the morning" so we left it. I followed her upstairs after a discrete delay and we kissed outside her room and stupidly(?) I said "I love you" and she said "I love you too" in a very sincere tone. I didn't want any awkwardness the next day, so I kissed her on the cheek and said "until the next time" and that was it. She seemed OK with that. I think my wife suspects something happened, as she was especially nice to me for a few days, but back to the cold shoulder in bed now 
So what now? I have been walking on air ever since and feel happier than I can remember. Don't know whether to make contact, or just remember it as a wonderful evening. I have since seen the photos of the evening and I am way out of my league with this woman anyway.
