Vinncenzo, unfortunately, it is the unintended consequence of her having another partner. This happens all the time, especially here. One partner wants/needs other partners and thus the marriage ends. A couple agrees to swing and makes the agreement of no emotional affairs. Oops, someone falls in love, runs off with the new partner.
He was never on board, didn't like it for 6-7 yrs, expressed it, plainly stated that by doing so, she risked his connection to her. She weighed the consequences, and to be true to herself and her nature, she continued. Hard to say what her response was in the first 7 yrs, but now her image of the relationship she wanted is slipping away fast.
KindaPOed, my impression is that under the new dynamic, long heart-to-heart conversations really don't happen, or rather, you were not interested in having them. Water under the bridge-type deal.
Have you flatly told Kate you have more attraction and love for your Julie and the reasons for that?
Does Kate know about this website?
Did she visit and read this thread?
Does she think you're a vindictive prick (specifically about this topic)?
I think it's easier to see this outside of the romantic-association context. It's a trick I use on myself to check my own actions for subconscious motivations when I feel challenged in my own relationships. Much of what builds resentments in romantic associations is due to our socialized view of caring for someone we are intimate with, and what they should or shouldn't do to show they care for us. We judge the people we claim we love most much more harshly than we tend to do with close friends. When we do to our friends what is more typical in romantic associations, it becomes more noticeable, even to ourselves.
We've all experienced the drifting apart of close friendships when we were growing up. A natural occurrence; circumstances make what used to be a strong connection weaken, and new ones get built. At what point is it natural when it is happening to announce to the friend who built a new association and their new friend that they should now be best friends instead of the original two? Especially when it was previously discussed that this is a possible outcome? When you want to wound them. Otherwise, it just happens quietly over time.
I watched my brother do this very thing when his best friend got chummy with another kid he took French lessons with. My brother spoke not a lick and began to suspect that when his BFF and the new friend would speak French in front of him that they were talking about him. Maybe they were and maybe they were not; it was never provable. That suspicion was what ended up killing the friendship before time could do it naturally. My brother began to act out to the BFF, causing the BFF to ask my brother why he was acting the way he was. Eventually, my brother announced to them both that they should be best friends now, because he was going to be best friends with someone he played hockey with. Very unnecessarily dramatic. They've long since stopped any contact at all.
I too have old friends I grew apart from over time, after a very close association, one of whom did behave like it was intentional-- their new friendship with someone else. KOP's words remind me very much of that dynamic. Others that I've drifted away from, or them from me, the dynamics were usually lacking, so those friendships faded without resentments or announcements to anyone who should or shouldn't be closest to whom, because it happened naturally.
Really, I'm not weighing in to make KOP feel bad about himself in this, but to caution how far this can go into ugliness, if he lets it. And I have no idea how all this is playing out in their home. None of us know if Kate is an emotional wreck trying to hold this together, or if he is only answering her concerns as she pushes him to tell her what's what. Just that he mentions staying with his wife for the child he has with her. That can be noble IF it is indeed to ensure the well-being of the child, and not to make the child stand witness to payback tactics. As he said, the kid isn't stupid. So, "staying for the child" can become pointless if it turns home life into a vindictive minefield. Staying with mum for the kid means staying with mum, not just residing in the same home. It means being there for mum when she needs him to be, because it's the example he wants his daughter to accept as a standard for her own relationships as an adult.
