Is anybody married & still got their exes trying to message them?

Like I'm fed up. My husband got his crazy ex from high school keep tries to message him even though he blocked her? He recently lost his mother unexpectedly.. but I know damn well my exes wouldn't care to even message me honestly. Like idk. But mostly it's been a problem before with another ex, whole different story that tried been talking to him a couple years ago. Why can't they be gone. We've been together nearly 5 years, married for 2. I just don't get it, like I have exes, they crazy, and they done moved on. But they can't move on from my mans. 💩😤
