I know a lot of parents feel this way - probably most actually. But I don’t. I love my DC, would unhesitatingly lay down my life for them, but DH is the one I chose. I made promises to him on our wedding day. I relate to @Loulou4022’s post.
(The following isn’t directed at OP btw) I can only speak for myself, and I get that it’s counterintuitive, but I feel like our three boys are going to be happiest and most secure if DH and me are rock solid in our relationship.
So that means that, as long as they are fed and safe and their emotional needs are broadly met, DH and I will make an effort to put each other first, and explain to the boys why we’re doing that.
I don’t ever want him to feel like he just gets the fag ends of my time and energy, once I’ve given the best of myself to the DC.
I’ve seen it happen too often that eventually both partners end up being sidelined in favour of their DC, and that is the death of their relationship.
Also, again only speaking personally, my sense is that it would do my children no good at all to feel like they are the number one most important thing in the family and that their needs should - and will - always be centred.
My feeling is that my boys need to know their place in the pecking order (I use this term lightly) Yes, they are of course important, but the survival and thriving of our family unit depends on their parents getting on.
That said, I completely understand that every person and every relationship is different. People need to do what works for them.
OP, hope this wasn’t a thread derail. 🙈 You raise an interesting issue and your post and the replies have been very thought-provoking - thank you. Wishing you all the best.
