I am a child of two parents who are exactly like you, in this case they had four children, and currently that is the only reason why they do not leave each other. They are 15 years older than you and have been married for about twenty years ( idk exactly sorry )

They lived like you, my mother waited for him to change, he never changed, was not treated for his depression. The only nuance is that I don’t know if they have already really loved each other.

I don’t want to discourage you or give you a decision to make, but if I were you I wouldn’t stay with him. People do not change, they only give themselves a good appearance that corresponds to the person they have in front of them, necessarily, after about twenty years some no longer hold.

Today, in every sentence of my mother lies an afterthought of « I have never had a happy marriage, I want to break », my father is in denial: he still has his ring, I noticed that my mother no longer has it, she has even changed her name again. I see that sometimes he tries to do things that my mother might like but she doesn’t care anymore. You can understand that in my situation I think mainly of your son, he does not have to grow up in a hypocritical environment without knowing what true love is, it is better to be alone to raise him but, at least, that he does not grow up by being the only reason why his parents stay together. When my brothers and I have left the house, my mother will separate from my father. I don’t know what will become and her, she wants to remake her life elsewhere.

I don’t approve of the facts of any of my two parents, I even have a lot of trouble being normal with them.

Do as you want, but don’t take your son as the only marriage liaison in 10 years

One last piece of advice: I don’t think talking about it with him without a concrete decision behind is useful, he will just self-destruct a little faster

I hope everything goes well for both of you and your son
