Guy confusion

Ok so I have met up with this guy four times and we get on so well, he is kinda busy at college so it is hard sometime to meet!! From past relationships and dating I am very insecure, so now that I am starting to really like him little things make me panic such as saying they are busy when they were not before and not giving specific days when they are free!! So my question is do you think he is just does not want to see me or he is generally interested from the language he is using (FYI I overanalysing everything so just what another perspective)

Thank you lovelies 😁😁

(Also there was conversation between when he sent these to messages)
