@dcaligirl,
Its impossible to tell without propper data. Unfortunately your account of the facts is most likely bias, I believe you should have more conversations as previously suggested. Some signs or tells you should look for him displaying are
• Him deepening his voice
• Making his stance bigger or wider
• Him leaning towards you
• Scratching his head
• Fiddling with stuff
• Glancing over at you
•Looking at you a lot , nodding a lot, general muttering and agreeing when talking to you
•Scratching his chin or face a lot
These are all indications he likes you but as there is no exact science to psychology and these sorts of tells even if he displays all (or none) of these, he may like you or he may not. The best thing to do is talk to him, get to know him better and see if you can get him to like you.
