Help!!!

Right I have been talking to this guy - I originally friend zoned him but after getting to know him have realised I like him!!! - so we have been talking and been seeing each other a bit (haven’t slept with him yet) however when we were drunk the other night he told me he did really like me and I told him the same , everything was still going fine etc etc , however we went out again on a Friday with our mates but then Day after he messaged me once in the morn and then I replied , ids been nearly 24 hours and still no response and his been on WhatsApp etc etc ??? I don’t know how to take it - do you think i should take it as his not interested or :( I was really starting to like him .....
