I screwed up after a great first date. Can I fix this?

I had a fantastic date with a guy I met online, after a few weeks of messaging, texting, calling. We really hit it off, and he was in contact right after, keeping things moving.
Right after that (days) several tragic things happened in my world—my best friend died, I had to take her kids on and off, my exhusband got diagnosed with cancer, had a huge work fiasco….needless to say I wasn’t at my best. I didn’t mention much about this to the guy, but was trying to still be in touch. Bad idea, because I wasn’t sleeping, was too stressed out…and my texts and messages weren’t giving a good impression (more of a desperate, frazzled impression). I even sent him a text meant for my friend and then was so embarrased I apologized and told him I would take him off my contacts but hoped he’d still be in touch. He took this as a blow off and told me I was great, good luck,etc.
I wrote to try to explain but he never responded. It’s been 6 weeks now, and I’m wondering if I should call him. I’d like to meet up with him face to face, so he can see I’m not actually crazy, but I“m not sure how to get him to meet me.
