Keep or delete?

I’ve deleted most, if not all, of the photos of me and my ex, and any time a memory pops up of him, i delete it. i have his phone number blocked, i have him blocked on all socials, we’re strangers strangers essentially… but i haven’t deleted our text messages… is that weird? i don’t go back and read them really, i think i’ve opened them maybe 2 times since we broke up in august, but should i delete them?
