I just met the guy and he won’t stop texting me is this normal

I really don’t know how to confront this guy about it, I just meet him at a college orientation and he seems like a good guy as I decided that it would be a good idea to exchanged social media. Okey how do I begin, I have being trying to be more nice and open as I really wanted to have a new beginning in college with a new circle of friends, I overlooked a couple thing like him taking a picture of me without my permission and also him, asking me if I wear glasses because he told me he got to look at my college ID, and his father saying that he could see me being his girlfriend which that weirded me out as I just meet him, but I ignored it, right away he started to make plans to hang out and well I responded to his text messages so I could get to now him more and not be jumping to conclusions, but I don’t like him texting me neither I want him to call me, he send me a lot of memes that are not funny and a lot of pictures of him and his animals to get my attention, we have a lot of thing in common but It stills make me uncomfortable that he text me in the morning, afternoon and night. I don’t want a relationship at the moment I told him that, and well i can tell when guys want something with me is obvious but he is just not taking the hint, I feel like it some type of commitment and is stressing me out as none of my guy friends do this shit to me and it bothers me when I don’t know people intention, I’m too blunt and i don’t want to hurt his feeling so I have being caution and my sister told me to stop texting him and just be acquaintances but the freaking dude wants to meet my mother and my abuelita... so i have being avoiding social media because of him and the only thing I don’t want is to create drama at the start of the school year, which I am so done as I want the school year to start at a positive note but I’m worry as there is going to be some tension. so how do I confront him about it so he can leave me alone the amount of text messages that he sends are overwhelming me and I need help as I don’t know how to deal with this as I never been in a relationship and i don’t want to be on one as I want to focus on myself ( I speak Spanish, and English is my second language I have not Idea about how to deal with Americans boys and i don’t know if this is normal😤 but I don’t want this kind of attention) please I need help I am inexperienced and i don’t know nothing about guys I just want him to stop
