Does he like me if he smile/laugh at me when we make eyecontact suddenly, tries to impress me, but doesn't text & said he's talking with someone else?

Or am I his second option? If he said that he was talking with someone to let me know just in case ( I think he knows I have a huge crush on him) but doesn't seem to be in a relationship yet nor seems to hang out with someone when he is free, then is he thinking between 2 girls? He spends like 2 hours at the gym with me 3 times per week and I feel we have some chemistry... should I ask him about how his relationship with the person he is "talking" to is going?
