To think children should always come before a marriage/relationship?

[Justdontgetitatall]

I was going to post this in Relationships, but couldn't find it on the app.

So, the comment on this video is mine -

Perhaps I was little harsh in my wording but I was very shocked at the as I am a single parent that is very protective of my child.

However, with the responses given in the video, I'm now starting to wonder if I was wrong to think my daughter should always have come before my relationship with her Dad and that maybe this had something to do with our relationship breaking down....?

This is really bugging me. Was I being unreasonable or is this a cultural thing and I was correct in thinking that kids should always take priority?

PLEASE be kind in your replies, I'm quite upset right now.

I'm not clicking on the video.

I feel slightly uneasy at the idea of a parent invariably prioritising a child over any other relationship, because the child might easily pick up on that.
