He said i love you to baby. But his voice sound like he was so tired. I want to know if he will speak again in his voice?

We can hear and often see them if not in real words in memories and living our life for them the way they would want us to.

Losing the person that is closest to you such as your spouse, is devastating at best.

I am sorry.

It is possible you heard your husbands proclamation of his love for you after his death.

I believe it can happen.
And it makes no difference if you heard it with your ears, your mind, or your heart .
The important thing is you heard it and felt the comfort it undoubtedly brought.

It may happen again ,
But be thankful it happened at all.
There are a multitude of people that give a lot to experience
What you already have.

I wish you well.
