Should I do this or forget it?

So three weeks ago I messaged a guy on this dating site saying "Hey how are?" and he said "Hey Im good, just busy with work and then school starts in late September." I responded with "Oh busy huh? Is that a blow off hahaha? Anyways I was wondering if you wanted to hang out or maybe you only like blondes?" He didn't respond and then I deleted that profile. I made a new one a day later and messaged "Hey I think I messaged you asking you to hang out and something else. So anyways, how's life?" and then he didn't get on for 3 weeks until this past Monday. He saw the message but didn't respond. I'm thinking of a final message saying "I'm never persistent with guys, but I saw we had alot in common and you seem like a decent guy so I'll try one last time. My name is _____ and you can find me on Facebook if you want." Should I or not?
I just won't do it. I told myself I'd delete it on Friday. I keep getting messages from guys that are very attractive but they don't seem to want anything substantial. Oh well, it's not meant to be. If I was meant to date him or even go on a first date with him then he'd have messaged me. Maybe the message I said asking him if he only liked blondes was stupid.
