the sudden realizations that they're really gone

does anyone else get those random moments where it hits you that they're actually gone? especially in the case where, like me, you were dumped and you went full no contact. it's been two months since the breakup and while I've been settling into the status quo without him, sometimes I just get really hit with the fact that he isn't a part of my life anymore. I'd scroll through the movies we watched together, look at the gifts he gave me, remember a spot we used to go to, and just be like damn. that really happened, and now it's over, isn't it? we grieve over our exes like we mourn the dead.
