Advice about blocking him and moving on? How can I realize I deserve better and be more confident in my self-worth?

Before the whole quarantine, I (22F) met up twice with a guy (25M) from Bumble three months ago and it was just a casual thing. And just recently out of nowhere, three months later, he messaged me and now just stopped responding. I was fine without contacting him for the three months and accepted that casual thing just faded due to this whole pandemic. Like I know he's no good and doesn't care and he only hit me up for a bootycall, why else would you text me after three whole months has passed? I'm still hurt even after months from his just not replying back to me in a timely manner, just like he always texted late and last minute to make plans.

I know it's just best for my own peace of mind to end this whole thing and block him and unmatch him. I just need a push so please just give me a pep talk that I need to stop being so dumb and end things? Any words of advice for me to stop allowing myself to me treated like this? It's so hard for me to realize my self worth and I just become weak at any bit of attention. 🙁
