<human>: Long story short, I've been on a date with a guy and it went well , but the texts after, not so much.

He became very insistant , I has to ask twice to stop texting so much on sunday because I wanted some quiet time on my own and would not have my cellphone with me.

The first date was on a saturday, and since it went well I told him we could see each other the following saturday... but he kept pushing to see me everyday, managed to know what I was doing from mutual friends and tried to invite himself. 

To give you an example I told him I would lay off the phone because I was visiting my dad and he kept insisting that I go see him afterward, while he knew I said no once, that I live quite a distance away and had work the next morning. By the end of the night I was thinking to myself '' noooooooo, argh!! '' when my phone buzzed.

He shoots 3-4 texts in a row all day long (I work 9 -17h30) and I had to tell him I would not be answering. 

Finaly I told him it was too much texts for me so he's now calling instead.

I feel like a bitch for raising his hopes with a good date and being turned off by the end of the week .... 

What can I do to make it more clear that this is WAY too much for me ?

It makes me a little sad because he is not a bad person but he completly kills it by this behavior, I feel like I've stuck my arm in a big machine..

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Guy who had potential is completely smothering me and I don't know how to ask him to cool down a bit without having to cut him off so soon .
