Husband cried in my arms

My husband had been drinking more than usual the past few days. Two nights ago after a few drinks he started talking about his mother who passed away when he was 16. He was sobbing so hard and he said “I just loved her so much”. I held him for an hour and I cried with him until he stopped crying.

I have been depressed since that night. I feel so bad for him. He never expressed this grief to me before. He has been a bit cold and distant with me ever since. Maybe he needs space? Anyone with similar experience I would appreciate advice. I want to help him but I don’t know what to say.

Thanks 💔
