relationship advice

Hi!! So I was being egged on to start talking to this guy and eventually we started talking after a night out in which we shifted, so we're still talking but I consistently doubt if I like him or not, I'm not sure whether to keep it going or end it but it's my first real almost relationship type so I'm just clueless!! After last weekend which we were together on a night out I felt like I liked him more but the talking has turned to shot now and I'm not sure what to do, any advice??
