Is there any hope for our relationship?

Good evening, The Magician
Things between my partner and me are tense. Several circumstances and a buildup of fatigue and misunderstanding have led to us either not speaking or, when we do, ending up in arguments. He just brought up the idea of separation. We have a 21-month-old daughter, and he has a 16-year-old son who is currently staying with us for the holidays. I do not want to separate; I just want us to get along and be able to raise our daughter in harmony. Does he still have feelings for me and want the same thing I do: to raise our daughter and be happy as a couple and as a family, which includes his son when he is around? It should be noted that since our little one was born, we have not had any time for ourselves, and our daughter is a strong-willed child who takes up a lot of our time (she has always been with us since birth). My parents, who could help us out, are far away, and my in-laws do not want to look after her.
Does our couple have a chance of surviving?

Thank you in advance.

Hello Milay13,

Your partner can no longer cope with the fatigue and stress, and with her teenage son in the midst of his growth spurt, it’s not easy to live with. In short, you no longer have time for anything, and especially not for dedicating yourselves to each other in terms of intimacy, and it’s starting to weigh on you.
What you lack above all is constructive dialogue, because right now everything is nothing but reproaches between you, which is why you argue.
We're not there yet, but it's true that in his mind he's thinking about separation. Everything can still be saved, and there's still a chance for your relationship to survive, but please dare to talk about it, just the two of you, so make time for these moments together!

Have a good day
The magician.

Thank you for your reply. It is true that we are all at our breaking point.
Sincerely.
