<human>: Provide a brief overview of the text.

I'm having trouble explaining to my H why this is bothering me so much.  Maybe I'm just being stupid.

A couple of years ago, we had what I refer to as "The Year Of Hell" where he basically treated me like absolute crap until I snapped and ended the marriage.  We ended up getting back together but it's slow progress.

One of the issues we had was that he had what he calls "a crush" and I call "significant feelings" for someone else during that time.  I noticed he'd completely emotionally checked out of the relationship for a while, and accused him of cheating... but I got the wrong girl.  He vigourously denied cheating (and still doesn't think it was cheating), which I suppose it technically wasn't, though I still feel betrayed that he lied to me by omission.  But that was only one small piece of the horrendous puzzle that lead us to breaking up.

However, it came up while we were having a good talk about our expectations for the future.  He's agreed that it was wrong to keep those feelings a secret from me, but where we differ is this: In my eyes, your partner having feelings for someone else is perfectly good grounds for ending the relationship.  Doesn't matter if they act on it or not - I want to be the one and only in a supposedly monogamous relationship, or what the hell is the point? He feels - very strongly - that having feelings for someone else doesn't prevent the relationship partner (ie, me) being his "one and only".  He says things like "But I would NEVER have left you" and "It didn't change how much I loved you"... and it seems so *logical*, when he puts it like that.  

But I can't shake this sick feeling in my stomach, and I don't know why.... or at least, I don't have the emotional intelligence to identify and articulate what I'm feeling.  I just know that I don't feel flattered, like he seems to think I should.  I feel like if you have feelings for someone else, the decent thing to do is end the relationship.
<bot>: He thinks it's okay to have feelings for someone else if your loyalty is with your partner - I don't.  Your thoughts?
