You don't like him
I know your post laurie was to brokenhearted, but I kind of feel the same way.
In that objectively, I can see that the LO is not a good, kind person. He is selfish, unfaithful, lacking in any morality or good manners, and has no sense of kindness. The opposite of me in many ways. So in that sense, it could be said I didn't/don't like him.
But actually I did/ do - because he is super charming and exciting and being with him was like being in a technicolour dream world. (This is really describing how limerence feels) Being with him was a moment of perfection. Plus add in lots of sexual chemistry.
This could be a feature of limerence in some cases, particularly with narcissists. That try to reconcile (i) the rational assessment that this LO is really a nasty piece of work that wouldn't make a good partner/husband/father with (ii) the emotional feeling that this LO makes the world a better place and makes you so emotionally high that there has to be good in him.
It really does your head in. I'm sure that to people who have never had this feeling the above sounds like a lot of daft gibberish. But as has been said above, the closest analogy is to to a euphoric adrenaline high that you get off a drug or adrenaline sports or similar.
I don't like him but at the same time I'm totally in love with him. Hooray for no contact.
