Unsure...😕

Isabel • Hebrew 13:5
Well I met this guy at school, I was studying before my exam and waiting for class. He walks up to me and asks..."Are you ready for the exam?" I say no because I was nervous about the test. 
So then we end up talking for a good hour before I had to go to class and he had to go to tutoring. But   While before he left he said maybe I could tutor you if you need any help in something, but not math... Because he was on his way to get tutored. 
Well he asked for my number and I gave it to him but before I have him my number he gave me his. He called my number ... I guess to make sure I didn't give him a fake one.... I don't know if I should trust him or give him a chance. He a college guy and ever since he's gotten my number he has texted me. I don't want to get involved because he'll be transferring to another school and I'm staying where I am. :/  
He's not even my type... When we text, he keeps it about school and just keeps the conversation going. I try to end it by "goodnight " or " have a good weekend " but he keeps texting. I don't know what to do? I would give him a chance but I still feel hurt by my ex's. Does he like me? What should I do?
