Articles like this are why hard scientists laugh at psychologists
"Three main chemicals are released during this initial stage of affair—dopamine, which is also activated by cocaine and nicotine; norepinephrine, otherwise known as adrenaline; and serotonin, one of love's most important chemicals."
These are exactly the same chemicals that are "released" when falling in love. Or when eating something sweet. Or going skydiving. You can draw no conclusions whatsoever about how "real" or otherwise the feelings in an affair are from this information.
(Also, cocaine does not RELEASE dopamine, it prevents it being reabsorbed and deactivated. Subtle but important distinction. Not sure about nicotine, but anyway....)
Much as I would chew broken glass before getting involved with a married man again, this I know - at some point in that f'ked up situation, L loved me. Maybe not much, maybe not for long and maybe not in a healthy way, but he did love me. And I loved him. The situation was foul, but the feelings weren't. Pretending otherwise would just be another form of justification and rationalising - and I did enough of that when I was IN the damn affair, so I'm sure as hell not going to do it now I'm free!
Echoing [Hidden] above, I wonder if people write and read these articles because the idea that people can fall in and out of love within a marriage is just too frightening to accept? Looking back to the time before me and my husband split up... it's hard to write this, but the truth is he fell out of love with me because of life circumstances that neither of us had the experience to handle. He didn't want to, but he did - and he fell in love with someone else. It was horrible, but it happens. And then I fell out of love with him too, that's why I could fall in love with L.
Now, I could choose to brush that reality aside and euphemistically call it "a bad patch" and that my feelings for L were just a product of my vulnerability, but that isn't going to be very helpful to us in the long term. I feel it's healthier to acknowledge that H and I fell out of love, broke up, stayed (mostly) friends and then through that friendship and (occasionally misguided) loyalty to each other, fell back in love again. Terrifying, messy, and largely uncontrollable. But reality as I see it, nonetheless.
