Is blocking guys wrong?

I’ve never had a boyfriend Bc honestly I haven’t met a guy was that interested in me to prove he wants something serious

However I’ve had a thing with a handful a guy

But it led up to me blocking every single of them

Keeps making excuses when I ask to hang out= block

Ignores my message for more than 20 hours but sees my story= block

If I feel any sort of mistreatment or that they don’t care that much = block

My friends say I go overboard but I don’t want to waste my time or give any guy any chances Bc I don’t want to spend my time on anybody that doesn’t care.

Do you think this going to make me single forever?
