OP, I recognise this.
My parents worked hard to give us a comfortable life. Far more comfortable than they had had. It did mean they focussed on material comfort rather than anything else. I still see this today when they are incredulous that someone wants to leave a marriage....but, but, they have a lovely house...!
My father worked away too. This is damaging to the child/parent bond. As an adult, I recognise he was an absent parent emotionally who thought his role was to provide a comfortable life for us all.
My mum saw her role as providing good food and clean clothes and a warm house. As you say, many have it worse.
But, there was no real emotional care. I was told I was loved as was my brother. He never believed it though.
I escaped through babysitting. I could be part of another family where they genuinely provided for each other emotionally. Once I was old enough, I left for Uni.
Your daughter is escaping through boyfriends and seeking that feeling of being cared for. Truly cared for. She knows what she wants to feel but she doesn't understand how to build it as she hasn't had that type of relationship before.
I'm sure your family is successful on the surface. You are giving your DC everything you never had. You maybe feel a little resentful that they do not appreciate all you have given them.
I begged my parents to attend family counselling with my brother and I but they could not understand what I was truly asking them for.
Your child needs something you cannot instinctively provide for her. You and your husband need therapy. I'm sure he will say he cannot because 'his job'. I heard it for 2 decades from my father.
You have a choice. This is a crossroads.
