Yeah, I completely get that
Already experienced it during our year of separation. That was quite rough. A relationship break up and losing my loved cat.

But, and I'm sorry, but it just spills out now...
He once came up to me overly excited and made some weird moves with his mouth, looking happy and full of expectation at me.
And I just couldn't figure out, what he wanted to tell me at that moment.
Until we both grew frustrated and I said, "sorry, I don't know what you want to say"
He stormed off, massively offended

Just hours later I realized, he tried to throw me kisses, like we did to him all the time, and he wanted to return the favor.

Although I extensively explained and excused myself, he never did it again.

Still breaks my heart, seeing him in my memory, how happy he was to show me something new he had learned. Even something he meant as an expression of love towards us.
And I just didn't get it in time...

Stuff like that still breaks me.

Thanks for hearing me out.
I could probably go on forever...
