Newbie - bf suddenly left after 9 years

[Italian]

Today my mother went to our town to sort out some stuff.

She called Ex to sort out what furniture he wants to take from the apartment, and he said he doesn't want anything - not the living room furniture that he bought himself, not the fridge that was a present from his parents. He just took the mattress from the bed, but we don't have any king size mattresses laying around, so she told him to take the whole thing and replace it with the queen size bed+mattress that we moved to the garage when we bought the new bed, a few months ago.

He got pissy and said he thought he was doing us a favour. Again, he didn't even bother to ask about me. Which in a way is good because my mother would chew him out if he did. And he probably knows that.

Then she called Ex's father, who did instead ask, and said they all miss me, but aren't talking about anything and minding their own business. She did mention that I was upset because none of them called or texted me, and he said - as I thought - that it's because they feel ashamed and don't know what to say.

It's normal, right? That the MLCers just turn their back on you after years of daily contact and seem not to give a [censored], like you just dropped off the face of the Earth, like you're worth less then a pet goldfish? Because even though I'm trying to tell myself that it's normal, I'm so pissed off that after 9 years he can just hurt me this badly and not even give a crap about it. Or look like it, anyway. I can't believe how you can be the closest person to someone for years and then be just happy never hearing from them again, but it's how it goes, right?
